NOTE FROM LOUIS: 
Please be sure that you have version 1.1 of this game, because version 1.1 has some improvements that are not in version 1.0. This is especially important if you can't see the colored Bird Notes in the beginning of the game. If you do not see those colored Bird Notes but you have version 1.1 (or higher) then please activate the "Hearing Aid" function in the options menu. When you activate the "Hearing Aid" function you will see those colored Bird Notes and you then will be able to open up the door in the top room of the Tower

Start a new game and click on options.You can adjust something here even if you are hard of hearing or color blind. On the tab you see the controls, the well-known WASD keys.L for the flashlight, J for the pocket PC and M for the menu.

You first see an intro film how you end up on the island.

You see a bird on a pole, green musical tones come out of its mouth. You also see the rocket fall.

Walk to the bird but it flies away, it has something in its mouth. The bird has flown to the tower, on the ground is a bronze plate with a sign.

Follow the path and go up the wide stairs, on the right you see a swamp with large blue mushrooms.

At the top you see a gate on the right in the rock. You arrive at a T-junction, on the right you go to the gate and also to the platform where the rocket is located. The left goes to the tower, you can also go up a staircase to a pagoda but it is closed.

Go left to the tower, go up the stairs and you are at the bottom of the tower. On the ground you see a drawing of a steering wheel with an anchor, take a good look at it.  You also see 4 lamps on the corners.

You cannot go further here because the door is locked. Turn around and go down, walk to the pagoda and turn right there and go down the wide stairs.

You go back to where the bird was. It may be night now, you will see the sign of the flashlight in the lower right corner. Click the L button to turn on the flashlight. You arrive at a T-junctionand you look out over the sea. On the left you go to the beach but you are not going there yet. Follow the path to the right, there are blue lights along the path. Just before the third lamp is a path to the right, enter it and follow it to the end.

You see a white lamp at a plateau there. In the bottom right corner of your screen you will see a sign appear, you have a radio message. Click on the J-key and your pocket-pc is in your screen, click on the antenna sign. You hear the message, it is difficult to understand but the text of the message is at the bottom.  Click with the right to store the pocket PC.Turn around and follow the path back to the other path, turn to the right.Follow the path to the bridge, you will see a thick pipe on the right.

Go to the right and walk between the strange square posts.

Turn to the left and there you will see a turning wheel on top of the pipe, click on that wheel and the wheel turns.

Walk back to the bridge, on the bridge you see the same sign as in front of the tower, a steering wheel with an anchor.There are 4 lamps on the corners of the bridge, each lamp has 4 characters.Now you have to look carefully at the position of the lamps, which sign is on which pole.Make a drawing of it because you need this at the tower.

Follow the path further until you see a kind of tent on the right.

Just past it you see wooden steps to that tent, it is a kind of playground / classroom.

On the left you see a cupboard and a table, in the cupboard is a drawing.

You get a magnifying glass at that, then click on the drawing.This will be shown on screen, click it away and the drawing will hang on a board on the right.There are only a few drawers in the cupboard, open them.You get a hand cursor, click with it on the drawer and it opens.

In the left you see a puzzle piece with a drawing of a fish.You can view this with the magnifying cursor.You see a purple ball in the right drawer, grab this ball At the bottom right you see a backpack with your mouse, the mouse wheel is red.This is your inventory and you can select things with the mouse wheel.

 Above the drawer with the purple sphere is a laptop, click on it to open it.Then click on the keyboard and you will hear a signal, at the bottom right is the sign of your PDA.You now get the first entry in the journal of P. Forté.

Read it through and then click the PDA away.Go to the table and there is a board and some puzzle pieces.

You can view and rotate them with the magnifying cursor, but you can't do anything else with it.

Walk to the other table, there is a note under the blue book. Click with the magnifier on the note and read it, then click away.

On the same table is a brown book on the right, also a note here. View it with the magnifying cursor and draw it. These are the numbers used on MYHA. Turn around and you see a drawing lying on the ground, click on the drawing. Click the drawing away and now the drawing is also on the board. To the right of this table is the board where the drawings will hang.

There is also a train on the ground, click on it and it runs a circle. Walk to the stairs, near a stone there is a card on the floor.

This also shows those characters.

Go to the path and go to the right, you will come to a planetarium with coloured and transparent spheres.

Walk the edge back to the wall. The control device is there. You can't do anything with it yet because there is no power. If you have looked carefully when you walked towards the wall, you may have seen the rocket lying. You cannot go from here to the rocket now because a part of the stairs is pulled up. Turn slightly to the left and you see a bird sitting on a pole. Walk towards it and you will see a symbol on the pole, draw this symbol and also note that the bird shows blue circles as tones.

 Turn around and follow the path back to the T-junction, turn left.

Go back to the tower, you will now open the door of the tower. There are lamps on the 4 corners of the landing, each lamp has 4 symbols. By clicking on a lamp you can turn the lamp, you now have to turn the right symbols forwards.

On the bridge you can see which symbol must be where.

If they are positioned correctly, the door will open, go inside.On the right is a bookcase, on the second shelf from below is a note.This shows the characters of the numbers from MYHA, note the characters.

In the fourth box on the third shelf is a drawing, click on the drawing with your magnifying- cursor.It is a drawing of the rocket with the door open. Click the drawing away.That is the next goal, open the rocket door but first you go up the tower. Go up the stairs, upstairs you'll find a chair with a cupboard in front of it. There are 4 balconies, 1 of which is closed with a fence. There is the bird with the green tones.

Go to the gate, on the right next to the gate is a switch. Click on it but unfortunately blocked. In the fence you see 5 round discs, when you click on a disc you see coloured tones. You now are going to find the birds so go down and leave the tower. Walk along the pagoda in the direction of the rock, you will see the door in the rock.

Turn slightly to the right and you will see a column with a symbol among the trees next to the rock. A bird sits on top of the column, you see white musical notes like the bird whistle. Note the symbol and also the white musical notes. Turn around and walk down the wide stairs, walk to the T-junction. Go to the left and via the stairs you come to the beach, go to the right.

Walk under the arch and a little further you see a few boulders on the beach on the left.

There you will find a bottle, click on it with your hand cursor.

The bottle is picked up, the cork goes out and you see a letter with a number of names. Click the bottle away and walk further, you will see another column with a bird. Walk through the water between the rocks and immediately turn right to the rock wall. There you will find a bottle behind boulders, also a letter with a number of names.

Turn around and walk towards the bird, make a drawing of the symbol on the column and what color music tones you see: light blue.

Turn around and walk back, on the rock on the right you see a stone in the shape of a fish.

Click with your hand cursor on the eye of the fish, at the bottom of the fish a drawer slides out.

This contains a drawing, a letter and a note with numbers and figures from MYHA.

Then walk back along the beach, under the arch, along the stairs.

Walk into the water and on the left between the rocks you will find another bottle, here too is a letter with names.

Then continue on the beach to the 2 jetties, walk up the left jetty. There is a stool in the right path, with a drawing on it.

Click the bottle away and then walk towards the tower, you will come to the start of the swamp. On the right is a column with a symbol, there is a bird on top of the column. Note the symbol and color of the musical notes: red.

Then walk back over the beach to the stairs, walk upstairs and then to the T-junction.

Go to the right and walk up, then go up in the tower.

Go to the fence and view the round discs, you have also seen the symbols on the columns of the birds

Through the symbols you know which color belongs to which disc. You find from left to right: light blue, red, green, white and blue circles.

Click on the discs until you have the correct color for each disc.

Then click on the switch and the gate slides upwards, there is a rectangular plate on the balcony.

Take that plate, you need it for the rocket.

On the edge of the balcony is a bird's nest, you get a magnifying glass on the nest. Click with the magnifying glass and you find a drawing.

Click the drawing away and the drawing goes to the board, also you see in that nest an orange ball. Take the ball. If you are standing on a balcony, turn around to the tower and look up at the eaves, where you can also see the figures from MYHA.

Go inside and look at the cupboard,

On the left is a letter, click on it with your magnifying cursor and read the letter. Click the letter away.

Then click on the map, top left you see a clue for the code of the box. A rock in the shape of a hand, a bow of a ship and a sea lion.

Click the card away and click on the letter on the right, read it. It is about storing / hiding important information. At the bottom right is written: The Chair. On the front of the cupboard you see 3 plates with a dot on them, when you click on an image a line will appear. If you click on it again, the character changes again, there are 24 characters on a plate.

These are the numbers 0 to 23, the 24 hours of the day.

With these numbers and logical thinking you are able to translate these signs into numbers. At the end of the walkthrough I have placed an image of the translation of a number of those notes. If you stand on the balconies you can see the rock, the boat and the sea lion but what do you do with it. Sit in the chair, the viewer is set up and you see that you are now looking from inside the pagoda.

The chair is linked to another chair in the pagoda.

From here you can't see the hand, the boat and the sea lion, so click right to get out of the chair. On one of the walls there is a cupboard with cables attached to it. Open the box, you will see a switch to the right. Click on the switch to put it to the left, unfortunately you get a short circuit.

You will also hear the signal that you have received a radio message. Click on the J button and then on the antenna sign on the PDA. Listen and read the message, problems with the generator.You must go find the generator. Go down and walk past the pagoda to the left, on the right you'll see the door in the rock near the red lights.

Walk further and there you will see the rocket, go down the stairs and walk to the rocket.

First walk to the tail of the rocket, there you will again receive a radio message. Click on J and listen and read the message.

Now walk to the rocket hatch, when you are close to the hatch you get the gear cursor.

Then select with your mouse wheel the plate that you have just found on the balcony and then click on the hatch.

Click with the arrow and you will enter. Turn to the left and walk to the sofa beds, on the right is a letter and also a laptop.

Read the letter and then click on the laptop to open it. Then click on the keyboard and you will receive another message in the diary. Read the message and click the PDA away. Under the laptop you see a drawer, click on the drawer and you will find another drawing.

Click on the drawing and then click it away, it will also hang on the board in the game room. There is also a drawer on the opposite side of the other bed, but there is nothing in it. You can also see a few paper figures there. Also you see a chair in the corner, you can sit in there but you get a message that you are missing a file. This is a part that didn’t make it to the final game.

Then walk to the other side of the rocket, on the left you see a red board.

Grab that plank, turn to the other side. There you will find a note and a calculator.

Click on the paper there you will find a formula to calculate the diameter of a planet.

Only which planet?  You can view more here but you can't do anything with it.You must now go find the generator so go out of the rocket.

Turn to the right and walk to the corner. The stairs is lifted up.

There is a lever on the rail for the stairs, click on the lever and the stairs will go down.

You can now walk around the island and from this side also reach the planetarium.  Turn around and walk along the rocket to the stairs, go to the door in the rock. Zoom in on the number panel, you will see a drawing of a fish, anI and a flower.

You have seen these drawings before on the puzzle pieces in the playground. You have to go back to the playground to solve this puzzle. You can go there in 2 ways, the shortest is along the rocket so go to the right. Walk to the corner and go down the stairs to the planetarium and then follow the path to the playground. You now have to put the puzzle pieces in the correct order, but unfortunately you cannot physically move them.

You have to take a good look at them and determine the correct order based on their shape. There are also 10 posts on the shelf and there are 11 puzzle pieces: the numbers 0 through 10. You find out that the fish is 8, the I is 1 and the flower is 3. The code for the door is 813. Look at the board on the wall, there are now 6 drawings hanging there.

Walk back through the planetarium, the stairs and along the rocket to the stone stairs. At the top you walk along the rock to the door in the rock. Go to the number panel, here you can see the MYHA figures. You have to translate the number 813 into those numbers, press the right buttons and the door slides open.

Go inside and turn around, you'll find another drawing on the right door.

Click with your hand cursor on the drawing and then click it away again. The drawing is now also on the board.

Turn around and walk further into the cave, across the bridge to the wooden door. 

Just after the bridge you see a lever on the floor on the left, stay away from that.

To the left of the wooden door, the corridor continues, enter it.

The corridor is not that long, you come to a table. It contains 3 letters / notes and a laptop.

Click on the first letter, it's a drawing. Click this way.

Click on the next letter, this is about a man calledRolan doing strange things.

Remember the name Rolan.

Behind the laptop you see another paper, these are again calculations with the numbers from MYHA.

Then click on the laptop with your hand cursor, then click on the keyboard.

You will receive an addition for the diary again, click on the J key and read the message. A little further you see a few dolls lying on the floor, you can view them. Turn around and walk back to the bridge and click on the lever. You see the mechanism turning under the wooden door, breaking off a plank.

Click the lever again and the mechanism will turn back. Walk to the door and you will now see the gear cursor on the bottom. Turn your mouse wheel until you see the red board, which you found in the rocket.

Click with the board at the bottom of the door and the board is placed in the brackets.

Go to the lever and click on it again, the mechanism will turn and the door will open.

Walk through the corridor and you will enter a large space, you will come to a circular walkway.

Go to the right and you will come to a path to the middle, on the right is a broken staircase.

Continue walking along the walkway and you will see a staircase on the right, below you see a cave.

Walk further and you will see another cave below, only no stairs but a barrier.

You now have to investigate those caves, continue walking until you reach the path to the middle again. Go to the platform, on the left you see a lot of candles. On the left you will find another drawing, click on it again and then click the drawing away again. This is now also on the board.

Then turn to the engine in the middle, you see 3 levers and a button.

The right lever is a brake, the lever in the middle determines what happens. Move the stairs down or move the stairs to the other cave.

The middle lever is blocked or released with the left lever. Slide the left lever to the left, then click the lever in the middle.

This lever has 3 positions: front, centre and rear.

With this lever forwards you can lower the stairs, with the lever to the rear then you move the stairs.

Make sure the lever is facing forward, then slide the left lever to the right.

Click on the right-hand lever to move it to the right, otherwise nothing will happen.

Now press the white button and the stairs will drop, when the engine stops click on the right lever to turn it to the left.

If you don't do this, the stairs will go up again.

Go to the walkway and go to the left, the barrier is up and you can go to the cave via the stairs.

Go down and walk into the cave, there is a chest.Click on it to open it, you will receive a radio message again.

Click on the J-key to hear and read this message.

Then click the PDA away, in the box is a green sphere and a letter. Take the globe and read the letter. Turn around and walk back to the engine in the middle. When you walk up the stairs you see another cave, you also see a yellow light in the cave.

Click on the right lever, it goes to the right and the stairs rise.

Slide the left lever to the left and then click twice on the middle lever, which is now backwards.

Move the left lever to the right again and click on the white button. You'll see the stairs going to the other cave.

Slide the left lever to the left and then click twice on the middle lever, which is now forwards.

Slide the left lever to the right and click on the white button.

When the engine stops, click on the right-hand lever to slide it to the left.

The stairs now goes to the other cave. Go over the walkway to the stairs and go down, walk down the corridor.

You have found the generator, immediately to the right you see another thick pipe with a rotary wheel.

Click on the rotary wheel.

Turn around to the control panel, you will see 9 plates with symbols.Below you see 9 lights, 4 are off and 5 are on.

You must now turn off a few things and turn on a few others. They cannot all be on because you will get overloaded.

You see the levers under the symbols, number them from left to right: 1 to 9.

Turn off 4, 6 and 7 and switch on 1, 2 and 3.

You now have power in the planetarium, the tower and the pagoda. The electric gate for the pagoda is now off.You are now ready for this moment, you have to switch things off later and switch them on again.

Go back up and out, it's time to search the pagoda.You see that the gate is now gone, go inside.

There you see the same chair as in the top of the tower.

Sit in it and you will see the same as in the chair in the tower, these 2 chairs are linked.

Behind the chair there is a gong and behind it you see an statue of a mermaid with a long tail. Walk towards the statue, when you are close you will receive a radio message again. Click the J button and listen to the message.

You see blue spheres in front of the statue at the right lap of fabric, where you get your hand cursor.

You then go to the back of the statue. Continue to almost the end and there you will find another drawing

Click on the drawing and then click it away, the drawing is now on the board. Turn around and walk back.

Go left again, go outside. There you see again a thick pipe with a rotary wheel along the platform.

Click on the rotary wheel to rotate it.

Then turn to the left and walk behind the pagoda.

Go through the opening and you see cables on the right, you also see a box with 3 lights and a switch.

Turn the switch to the right, the seats are no longer connected. Go back into the pagoda and sit on the chair, you will see that it is now connected to a space telescope. You have to measure distances and angles of planets with this, but you don't know which planets yet.

Go back to the chair in the tower, do not sit in the chair yet but first go to the box with the 3 lights and the switch.

Turn the switch to the left, now you will not get a short circuit.

Sit in the chair, you now look through binoculars on top of the tower. On the map you have seen the clue, a rock in the shape of a hand, a bow of a ship and a sea lion. Look with the viewer for the hand-rock, put the rock in the middle of the screen and get out of the chair.

Look at the ceiling and there you will see an arrow pointing to 1 of the balconies.

Go to that balcony and turn around, look at the eaves. You see a hook that indicates a number.

Note this sign, this is the sign for 7.

Sit back in the chair and turn the viewer to the left, there you will see the bow of a sunken ship.

Place the bow in the centre of your screen and get out of the chair.

Look again at the ceiling to see which balcony the arrow points to. Go to that balcony and look again at the eaves, the hook indicates another sign.

Note the mark, this is the mark for 13.

Sit back in the chair and turn the viewer further to the left. You will find the sea lion on the other side of the rock.

Place this in the centre of your screen and get out of the chair.

Look up and go to the balcony where the arrow points.

Note the character that indicates the hook, this is the character for 21.

Go to the cupboard and click on the left button until you see the hand-rock sign.

Then click on the middle button until you see the sign of the ship's bow.

Then click on the right button until you see the sign of the sea lion.

The drawer opens, you will find a red sphere there. Take the ball, you also see a tube. Take the tube too. You have to enter a word here, in the letter here on the box you read that someone wanted to hide information. In the cave you read in a letter that it is Rolan who wanted to do this.

Turn the rollers so that you readRolan there, the case opens. Click on the letter to read it, at the bottom you can read that the coloured spheres are important.

The size of the planets is also important.

At the very bottom you see a number, 8517. This is the code for another cave.

Here you are ready, go down and then to the planetarium. Walk past the pagoda to the rocket and then via the stairs to the planetarium.

You must restore the constellation here. There are 2 rings with 8 circles on each ring, you must first turn the rings into the correct position. Then you have to turn the circles well. On the left at the wall you see a round plateau with a railing.

Go there and step onto the plateau, you will see a control panel on the railing.

At the bottom you see the buttonsE and F, click on them and a drawer slides open.

Here you will find a letter and a yellow sphere, grab the sphere and read the letter.

Click away the letter and click button E or F to close the drawer. 

You can see a slider between E and F, which has 9 positions: 0 to 8. With this you select the rings or 2 circles.

At the top left you see a button G, with which you can raise and lower the platform.

At the top right you see a slider with 3 positions H1, H2 and H3, with this button you select a ring or a circle.

H1 is for the inner ring or the inner circle, H2 is for the outer ring or the outer circle.

With H3 you select both of them.

Buttons I and J speak for themselves, with this you can turn a ring or a circle.

I made a drawing of the planetarium where you can see if the rings are positioned correctly.

Raise the platform, the K slide is now at position 0.

This is to turn the rings.

First you turn the outer ring well, so you have to turn knob H to H2.

Then look at point A, where you can see if the ring has been turned to the correct position. You can see point A well from the platform.

Click on button I or J to turn the ring, I turns left and J turns right.

Now turn the inner ring to the correct position.

Click on button H, this must be on H1. You have to click button H twice to put the button on H1.

Then look at point D, where you can see if the inner ring is in the correct position

Click button I or J again to turn the ring.

If the rings are positioned correctly you will see the coloured spheres as shown in the drawing.

You still have to turn the circles to set the constellation correctly.

Now click on button K to put it on position 1, now you can rotate the circles on position 1, you see them at point A.

You can clearly see from the platform how to rotate the circles.

You must switch with button H between H1 and H2 to set the inner and outer circle correctly.

 

Are these 2 circles correct then click on button K, this goes to position 2.

Now also set these 2 circles correctly and then click again on button K, this will go to position 3.

This way you can turn the circles right up to position 4 from the platform.

For the other position you have to lower the platform and walk to the positions.

Then note at each position which circle to rotate and how many degrees.

After 8x click on button I or 8x on button J then a circle is rotated 360 degrees.

When you have noted everything, walk back to the control panel to rotate the different circles.

When you have done all this, walk around the planetarium to check that the constellation is restored.

All lines must connect.

If everything is correct, go to a pillar and look through the hole in the pillar from outside to inside. You will then see a coloured sphere, step back and look at the base of the pillar. The arrow points to a number, note the sign that you see there and also which color sphere. Do this at all pillars and note which color sphere you see and what number you see at the bottom of the pillar.

Now you know which planets you need. In the letter that was hidden in the tube in the drawer in the tower, you read that the size of the planets is important. In the rocket is a calculator and a diagram to determine the diameter of the planets. So walk up to the rocket and go inside, go to the right and click on the calculator.

On the paper you see that you must know the distance to the planet. You also need to know the angle between the left and right sides of the planet. You also see the formula that you must use. Go to the pagoda and sit in the chair, then find the yellow planet.

First point the viewer's centre at the left edge and note the number of degrees that the viewer indicates. Then aim at the right edge and note the number of degrees again. Now place the white dot in the centre of the planet and note the distance that is under the triangle.

You have to look carefully but there is a decimal point, you don't need the decimals Also at the angles there is a decimal point, this you also don’t need.

Do the same for the other planets, the blue one is a bit harder because it revolves around the green planet.

If you have the data for the yellow, blue, green and red planet, go back to the rocket.

Click on the calculator, turn on the calculator.

Grab the data, start with the yellow planet.

Subtract the number from the left and right sides of each other and you will find that the angle is ± 3 degrees.

Enter this in the calculator and then click on the RAD button, you have then converted the angle to radians.

This is also a method to indicate angles.

Now multiply this number by the distance, for yellow this is ± 104800.

It is not all that precise, the result is ± 5485.

Do the same for the other planets.

Later you will see why you have to rounded the diameter.

Leave the rocket and go to the generator in the cave, move lever 1, 2 and 3 up.

Now move lever 8 downwards, otherwise you will have no power in the cave to which you are going now.

Now go back outside and then to the beach, go left. Then go left to the swamp, following the wooden path.

At the first side path to the right you see a thick pipe, go the path and turn to the left.

There you see another rotary wheel on the thick pipe, click on the rotary wheel.

Go back to the main path and continue to the right.

Follow the path further until you reach a large heavy door in the rock, on the left is a code lock.

On the letter in the case was a number at the bottom: 8517 Enter this code, you have to translate these numbers to the numbers of MYHA. It is not that difficult, from bottom to top and from left to right, the numbers 0 to 9 are shown here. You also get a radio message again, click the J button and listen and read the message. When the door is open, follow the corridor until you see a door on the right, next to it is a broken window.

Use your flashlight and shine in the hole in the window.

You see a letter and to the left of it you see a button, click on the button and the lights come on.

On the left side of the wall you see a poster hanging on the wall. You now need the numbers that you have found at the bottom of the pillars along the planetarium. On this poster you can see which symbol belongs to which planet. Read the letter, then click on the 2 buttons below the green button. The first becomes green and the second becomes red.

In the middle you see another button and on the right a slider with 3 positions.

Now click on the button in the middle, the button next to the slider turns red.

Move the slider to position 2 and click the button in the middle again, the button next to the slider also turns red.

Move the slider down and press the button in the middle, now the button next to the slider turns green.

You will then see a capsule / pod going left over a rail.

Turn to the left and you will see an exit, walk to the exit and go outside.

You see the capsule come to the left along the rail and the capsule is placed on a platform.

4 supports are now being raised.

Walk to the capsule and go to the back, there you will get the last radio message.

Click the J button to hear and read the message. Click on the hatch on the back of the capsule.

Above left you see the same diagram as in the control room, below that you see 4 cavities with symbols.

You should now have 6 coloured spheres in your inventory. On the poster you can look up which color belongs to each symbol.

Stand on a cavity with your cursor and you will get the gear cursor, then select the correct sphere by turning your mouse wheel. When you see the right sphere, click with your left mouse button. Top left should be yellow, top right red, bottom left blue and bottom right green.

On the right you see another sliding panel, 4 slots and 4 symbols and also 3 yellow stripes.

Here you must enter the diameter of the planets, now you see why you have to round.

You can only take steps of 2500.

The bottom is 0, the first line is 5000, the second line is 10000 and the top line is 15000.

You know the diameter of each planet and also which symbol belongs to the planet.

Move the triangles with the symbols to the right place.

Then go to the front and click on the white button.

If you have done everything right, the button will turn green and a drawer will open at the bottom.

Read the letter that lies there, click it back and then take the "Black Cube".

Sit back and watch the final film.
