The rooms and items in these levels are randomized. The layout for you may not be the same as in this walkthrough. The puzzles and general progression route, however, will remain the same.
Table of contents
The Prisoner
You’ll wake up in the Imaginary Prison. Loot the two Old Chests and break the two barrels in the room for some items. When you’re ready, head through the exit. Up ahead, you’ll find a large barrier of light blocking the way.
As you approach, Tutu will fly in. Run through her dialogue and watch as she breaks the barrier, allowing you to pass through.
You’ll enter a large dining room. A man in a suit will walk in from the kitchen at this point. This is the Prisoner, and he clearly has a grudge against Tutu.
Let the cutscene play out and you’ll eventually learn that Tutu is the one who killed Thomas. Learning this secret, Amy will banish her.
After this the Prisoner will head for the kitchen allowing you to move around the house freely.
There are four rooms that you can get to from the dining area
- The bottom-left door leads outside to a bench. Amy will notice a bricked-up window here.
- The top-left door is locked. But Amy hears a Thud inside when she tries to open it.
- The top-right room leads to the kitchen, where you can speak to the Prisoner.
- The bottom-right door leads to a water fountain.
You’ll find a Chalice on a table beside the fireplace in the dining area.
Fill it with water from the fountain, then pour it onto the fireplace to extinguish the flames.
As the Prisoner comes to reignite the fireplace, quickly run into the kitchen. On the table inside, you’ll spot a Golden Key. Pick it up before the Prisoner returns.
Once you have the key, talk to the Prisoner and run through his full conversation. When it’s done, a portal will open near the dining table, allowing you to return to the real world.
The Wounded Guardian
Before using the portal, unlock the top-left door with the Golden Key.
Head inside to find a guardian chained up to the wall. It becomes clear the Prisoner has been exploiting her power for his own gain.
At this point, the Prisoner comes in and a boss fight begins. This is a tough battle, as you’ll face both the Prisoner and the Guardian together. Focus on the Guardian first as she can continuously heal the Prisoner, making the fight drag on if she isn’t dealt with.
After the fight, speak with the Wounded Guardian. She will give you the Guardian’s Light before fading away. This is an important item that unlocks an alternate ending for the game.
Talk to the Prisoner one last time and then escape through the portal as the monsters get inside.
The Lighthouse
This chapter begins immediately after exiting the portal from the Prisoner’s house. You’ll wake up back in the apartment, and this time you don’t need to interact with the Electrode Cap on the bed.
The Shadow People Ambush
As Amy wakes up in the real world, she hears someone ringing the doorbell. Open the apartment door to find Tutu waiting outside
She steps inside and warns you that the Shadow People are coming. Run through her dialogue as the apartment begins to disintegrate around you.
Eventually you get interrupted and the Shadow People break inside. While Tutu holds them off, you must run toward the balcony at the far end of the apartment.
Click outside to jump off the balcony.
The Beach
You’ll wash up on the shore of a beach. Pick up the Flashlight nearby and head east to the next section.
In the next area, you’ll notice a Fishing Net hanging on a wooden pole. Collect it and continue east.
In the following area, you’ll find a Metal Box on the ground. We found a Can of Meat inside it.
Keep moving east and you’ll spot a Pickaxe impaled on the rocks. Collect it and interact with the door. It’s locked for now.Â
Double back to the spot where you first woke up and start heading west.
In the first area to the west, you’ll see a hole in the ground. Use the Fishing Net to create a makeshift ladder, then climb down.
Through the door below, you’ll enter a large and dark Egyptian chamber with red and blue tiles on the floor. For now, there’s nothing you can do here, so head back outside.
Continue west to find a cave entrance blocked by rubble. Use the Pickaxe to clear the way and head inside.
Enter through the hole on the wall to find yourself back at the hotel.
Exit through the door to reach the Reception Area.
Behind the counter, you’ll notice a Golden Key hanging on the rack.
As soon as you take it, the hotel lights begin to explode. Run back outside and sprint toward the locked door you saw earlier on the eastern beach.
Use the Golden Key to unlock it and head inside.
This leads you to the main lighthouse. Pick up the Blue Crystal.Â
The head straight for the egyption chamber that you found earlier. Ignore the Shadow People coming from the sea. They can’t reach you yet.
Use the Blue Crystal with the Scarab Relief at the top of the chamber. This will light up the room and cause blocks to rise on the tiled floor in the center.
The Rolling Boulder Puzzle
In the center of the chamber, you’ll notice a boulder resting on the left side of the tiled floor. Your objective is to roll the boulder across the tiles and land it on the far-right spot.
You can interact with the boulder from any side, but once pushed, it will keep rolling in that direction until it hits a block. If the boulder rolls off the tiles, it will shatter, and you’ll need to restart the puzzle.
We’ve marked the correct path in the image above if you’re struggling with the solution.
Once you solve the puzzle, the blocks will disappear, and the Blue Crystal will glow brightly.
Head back to the Lighthouse. You’ll find Tutu waiting inside. Run through her dialogue to complete the chapter.
The Library
As the last chapter ends, you’ll find yourself back at the Lighthouse. Tutu is back to full strength. Interact with the Electrode Cap on the bed and choose the Library as your next destination.
Entering the Library
You’ll wake up outside a tent in a desert area. Loot the backpack next to you for an item. We found a screwdriver. You can spot a tall tower in the distance. Continue along the path to the east.
This takes you to the entrance of the Library. Enter through the large door to go inside.
The first room in the library has two old chests that you can loot. We found a Trash Can Lid and some Nailed Planks. There are two paths you can take from here: east and west.
The Western Path
The western path from the entrance takes us to a room with a patrolling Jailer. We can avoid it by staying off its path.
The path forks off southwest and northwest. We’ll head northwest first to reach the Librarian’s room.
Run through his dialogues and he’ll hand you a Golden Key. Take the southern exit from this room. This room connects to the southwest exit of the previous room.
This room also has a Jailer that you can avoid. There are two exits here: south and southwest.
Take the southern exit to reach a room with a pile of bones on the ground. You can loot it for a Human Bone. There’s a backpack right next to it. We found a Cleaver inside it.
Return to the previous room and take the southwestern exit. This brings you to a room with five paintings on the wall. You can see four hooks to hang two more paintings.
Run to the lower side of the room to find another painting on the ground. Pick it up and hang it on the wall.
Continue west to find an NPC at the far end of the room. Talk to the NPC and he’ll ask you to be quiet. But no matter what you do, he keeps saying he can hear you.
At this point you can turn off the volume from the game’s settings. Talk to the NPC now and he’ll tell you that you’ve finally quieted down. He will give an Eye of Horus Amulet. This is an optional item, but it’s the best healing item in the game. The NPC will walk off after handing you the item.
There are two more exits in the room, one leading north and one to the south.
The southern door brings us to a circular room with a map on the wall. Pick up the map and head for the northern exit from the previous room.
You’ll reach another room with a patrolling Jailer circling around a bookshelf. Loop around him and head for the northern exit.
In the next room, you’ll find a bookshelf with a missing book in the north.
Interacting with it reveals some weird symbols in the missing book’s slot.
With that done, head back to the library entrance. We’ll take the eastern path next.
The Painting Puzzle
The first room to the east has a locked door in the north. Use the Golden Key that the Librarian gave you to unlock the door and head inside.
You’ll reach a safe zone with a wardrobe and a metal chest you can loot. There’s a coffee pot here that you can use to restore Focus.
But the important thing here is the painting hanging on the wall. Interact with it and pick it up.
With the Painting in your hand, head back to the room with the paintings on the wall. You can now hang the final painting on the wall but nothing happens.
To solve the puzzle you need to arrange the paintings in a way that they form a complete picture. Check the image above for the solution to this puzzle. Once you solve the puzzle you’ll hear a sound.
Head to the lower side of the room to find a secret door open on the wall. There are three books inside. Pick them up.
Examine the book titled The Key to Success. Rotate it and press the button at the back of the book. Amy will say that it isn’t an ordinary book and she can push something here.
Interact with the book once again to reveal three symbols on the book. This matches up with the symbols you saw on the bookshelf with a missing book.
The Bookshelf Puzzle
Return to the room with the bookshelf that has a missing book. Check the symbols inside the slot.
You need to line up the symbols on the book in your inventory so that you can push it into the missing slot.
The solution to this puzzle is as follows:
- The arrow at the top of the book should face away from the cover.
- The arrow in the middle of the book should face towards the cover.
- The arrow at the bottom should face toward the opening side of the book.
Use the book with the bookshelf, and it will fit into place.
The bookshelf will drop into the floor, revealing a hidden path behind it. Go through it.
Continue heading north through the next few rooms until you reach a room with a statue in the middle.
The Book Stacking Puzzle
Interact with the statue up ahead and pick up the Crown.
There’s a stack of books on the table. Check it to see the names of the books. Note the color of the books and the number mentioned in each of them. Interacting with a book puts it at the top of the stack.
Now examine the Crown you picked up from your inventory.
You’ll notice that the number of gems on the Crown matches up with the books on the table. To solve the puzzle, you have to line up the books in the order shown on the Crown.
For us, the sequence from top to bottom was as follows:
- Devil of the Pentagram
- The Eighth Wonder of the World
- The Holy Trinity
- The Four Seasons
- The Seven Deadly Sins
Once you stack the books in the correct order, the sign on the north wall will open, revealing another hidden door inside.
Head through and continue north to the next room.
Keep moving north and you’ll find yourself in a room with a Glass Dome at the end. Use any weapon in your inventory to break open the Glass Dome and loot the chest inside it. You’ll find a book titled The Fate of Thomas.
At this point, three Jailers will walk into the room. Examine the book in your inventory.
This will open a portal, but it’s on the other side of the Jailers. With no other options left, you must fight and defeat them.
Once that’s done, interact with the portal to return to the Lighthouse.
