• Part 1
• Second playthrough

Sticker puzzle

Return to the room with the TV. Click on the piece of paper in front of the boy to see the outline of a cube surrounded by stickers.

Start by placing the red triangle on the lower left square.

Select the hourglass sticker from your inventory and place it on the box diagonally to the right of the red triangle.

Place the x-shaped sticker to the left of the hourglass.

Select the planet sticker from your inventory and place it in the rightmost box.

Place the hand sticker in the box above the x-shaped one.

To complete the puzzle, place the bird sticker between the planet and the hourglass stickers.

Once the sticker puzzle is completed, the boy will pull out a miniature pyramid that can be placed into your inventory.

Mini pyramid fish puzzle

In the lunch room, give the mini pyramid to the boy sitting at the table.

This will shine a rainbow onto the fish, turning it into a living one. The boy will leave the knife on his plate, which can be grabbed.

This will also cause the window behind the laboratory to open, revealing a new room.

At this time, the brown controller can be given to the lab assistant.

They will use it to open the second container, which contains a plant seed.

Ouroboros puzzle

The Ouroboros room can be found behind the laboratory.

Select the red pearl and place it into the red-eyed dragon's mouth.

This changes the ouroboros painting in the back into a puzzle.

This puzzle involves rotating the platforms so that the red ball collects all of the blue ones before landing in the hole.

The solution to the puzzle is shown in the image below.

The completion of the puzzle causes the blue-eyed dragon to spit out a blue pearl.

Blue pearl puzzle

The blue pearl can be placed into the hole on the strange stone hill.

This will turn the lines on the hill blue and open up the doorway.

Entering it reveals a second doorway and a campfire, which can be placed into your inventory.

Secret door puzzle

The lock on the door is a series of hexagons with circular holes. To complete the puzzle, all of the holes on each hexagon need to be lit up.

To get the lights in the center of each hexagon to line up, they must be touched by hexagons containing the same number of holes on their edges. Start by placing the five-hole hexagon in the center of the middle row and moving the hexagon with two holes on the outer edge to the lower right of the fice-hole one.

Move the hexagon with two central holes to the leftmost hole of the bottom row. Place the final hexagon, with one hole in the center, to the right of the previously placed one.

The door will open up to a secret chamber, giving players the "Open Sesame!" achievement. The axe in this chamber can be grabbed.

The marking on the left side of the floor is the same marking shown being dug up on the TV in the room containing the sticker puzzle.

Using the shovel on this piece of land will unearth a Sun rune.

Plant seed puzzle

On the first floor of the spaceship, place the plant seed into the flames of the left barrel.

The seed will sprout into a lotus, which can be safely grabbed from the container.

Spaceship second-floor wooden puzzle

The flower-shaped puzzle on the second floor requires switching certain parts to white while leaving the rest red.

To discover the pattern, the knife must be used on the apple.

The red and white pattern of the seeds indicates the solution for the wood box.

The pattern on the box will look like the image below when it is correctly completed.

With the completion of this puzzle, the molecules in the nearby puzzle will move wildly before transforming into a white bird.

Obtain prayer beads

In the dining room, trade the coin in your inventory for the man's prayer beads.

Rune puzzle

Travel to the room containing a ringed planet with the words "Dark Side of the Moon" on it. It can be found to the right of the original room, the Mysterious Room.

Set the sun rune on the floor marking that looks like a sun.

Put the moon rune in the rightmost space.

Place the star rune on the remaining spot. This will cause a red car to drive around the ring.

Red vehicle puzzle

Clicking on the red vehicle shows that it is a taxi with a mysterious man driving.

Tapping on the broken front window exposes a puzzle with seven different symbols.

Each of these symbols correlates to a sign in the next room over.

From left to right, the number of dots above each symbol should be 3, 8, 4, 2, 1, 7, and 5.

This will cause the car to drive in circles around the planet's ring, dropping a scribble paper for your inventory. It will also unlock the "Round-the-World Travel" achievement.

Bird carving puzzle

In the area containing the radio tower, a bird can be seen carved into the stone.

This will open a compartment beneath the wing containing two holes. Place the starfish fossil into the first hole.

Place the ichthyolite into the second hole.

This will turn the radio tower on, scaring the bird away.

Furnace puzzle

In the engine room, place the firewood from the campfire into the furnace.

Talk to the mechanic afterward to get an iron ball.

Continuing to talk to the mechanic will lead to him mentioning deer and autumn leaves.

Visiting the room with the deer afterward will give you the "Autumn is in the Air" achievement.

Iron ball puzzle

Talking to the boy after getting the iron ball results in him asking you to check the upper hole.

The iron ball can be dropped into the top hole.

He will get an item and begin talking about how he just wanted to find a badge.

By giving him the badge from the lighthouse, you can obtain ivory.

Grab the iron ball again and drop it into the leftmost hole to get a blue controller.

Nirvana puzzle

Behind the musician's room is a room belonging to a man seeking Nirvana. The art on the wall appears to be of the Hindu god Ganesha, with each of the portraits holding two items. These items depict the items needed as well as the circles they need to be placed in.

Start by placing the ivory on the back right circle.

Then set the axe in the back left circle.

The lotus flower fills the front right circle.

This will cause the man to reach Nirvana, producing a green photosphere and unlocking the "Raiders of the Isoland" achievement.

Alien tentacle puzzle

Hand the researcher the blue controller.

This will unlock the pod holding the tentacle, which can now be grabbed.

The stone alien near the spaceship has a cut-off tentacle that has a matching red color on the edge. Select the tentacle and attach it here.

The geometric shape on the alien's hand will turn into a bird, clearing the "Sleeping Bird" achievement.

Looking at the tree in front of the cabin after freeing this bird will additionally unlock the "Birds of a Feather Flock Together" achievement.

Photosphere puzzle

By the outdoor staircase, a statue holds a broken handle with a green glow at the top.

Place the green photosphere on top of this handle.

A series of symbols will be revealed where the statue once was, plus a door will appear on top of the stairs.

Staircase door puzzles

The lock on the door features five symbols and the numbers 1 through 4.

These numbers correspond to how many times each symbol appears on the wall. The sun appears once, the moon three times, the planet once, eyes twice, and the star appears four times.

Entering the doorway reveals a campfire on the edge of a stone landscape.

Place the ship's picture into this fire.

This will give you a bidirectional ring.

Secret chamber bird puzzle

Before heading to the puzzle, look at the four birds on the tree. Take note of how many leaves are in each bird's section.

Each blue dial correlates to a specific bird, differentiated by each bird's appearance. The leaf in the center implies that the number relies specifically on the number of leaves.

The bottom right dial correlates to the bird on the top left branch, which contains 8 leaves.

The top left dial correlates to the lower left bird, whose branch contains six leaves.

The top right dial correlates to the bird on the top right branch, whose branch contains ten leaves in total. The bottom right bird is the bird that can be found on the lower right of the tree. That branch contains eight leaves as well, so the dial should match the dial to its left.

Solving this unlocks a mysterious floating suitcase.

Click on the suitcase to open it, revealing a staircase.

The room at the bottom of the staircase contains a bed with a book on top of it.

Place the bidirectional ring into the grooves on the book to complete the game and unlock the "Return to the Stars" achievement.
