Chapter 2: Chess puzzle
To solve the puzzle, you must first collect all the vertices of the chess pieces. The first top (Tower) is the flat piece you used to enter the room.
Collect the tower and place it on the left chess piece of the board. You can now climb to the top and collect the king. Go to the far right of the room - pass the map with a scrawled red eye - and jump into the closet to retrieve the queen.
We must now subdue the Dark Queen. Place the queen at the back left. Place the tower in the right place. Place the king in the center front. Use the image above for reference.
Once all the pieces are in place, the lights will come on. Use the Tower to climb on the right table and hang the light to open a secret door with the key you need to progress.
Chapter 3: X-ray puzzle
At the start of the hospital, you will enter a large multi-story room. On the lower floor, go right to find the exam room with an x-ray machine. Continue right and you will find a room with three teddy bears.
One of the teddy bears contains the key. Check the three teddy bears by taking them to the x-ray and turning it on with the switch. Once you find the teddy bear with the key inside, take it and walk to the elevator.
Go down the elevator, then throw the bear into the incinerator on the right. Pull the switch near the incinerator door to burn it - you can now retrieve the key from inside.
Chapter 4: Elevator Puzzle
In the building you will come to an elevator in a ruined well. To solve this puzzle you need to press the elevator switch and go up - the upstairs door is locked.
To bypass the lock, press the elevator switch and jump to the right. There is an upper ledge with stairs that you can use to reach the upper floor. Open the desk drawer to get the key and unlock the elevator door.
Once you find your friend, get on the elevator again and use the switch to go down. As the elevator goes down, jump and reach the crawl space stairs going up - you have to go back to the top floor and use your friend to reach the elevated switch that reminds you of the elevator.
Once you're both in the upper hallway and the elevator is downstairs, use the elevated switch to call back to the elevator. Jump on the roof of the elevator on its return to reach the maintenance area and progress further.
Chapter 5: Purple Door Maze Puzzle
You will find endless doors that seem to teleport you for no rhyme or reason. To progress, you just need to listen to the music - follow the music and enter through the doors where the music is loudest. You will have to enter several doors in a row and sometimes return to the doors you just went through.
For the four-door hallway, be sure to push the left front door to open the right rear door. It makes sense!
In the long hallway with the hole in the center, push the post down to create a bridge across the middle so you can access all of the doors.
