If you go through the Cyan door with Alice, you end up in the Crew Quarters.
In room 2, there is a key part on the desk.
In room 4, there is another key part on the desk.
Combine the two key parts to make a key. Use it on the handcuffs on room 3's door.
Take the box cutter from the room 3 desk.
Make Some Calls
Go into room 1 and touch the phone. Press 2 to call Alice. She says her phone shows 25**.
Use the phone again and press 4 to call Phi. She sees **92 on the phone.
You can also enter some secret numbers for amusing results: 8008 ("boob") gives you an upside-down message that says "Gosh he is illegible! O'Leigh." If you call 5309, Jenny will answer (a reference to a song called "867-5309/Jenny"). If you call 3141 (the first four digits of π ...not to be confused with Phi), you hear a message from Euler. If you call 6969, well... just try it.
Load Up the Tape
The locker in room 3 is unlocked, so open it. Take out the aluminum foil and use the box cutter on it multiple times until you have four patterns.
Put the correct pattern into the room 2 desk to get the code 4985. Use this code on the locker in room 2 to get a cassette tape. Go put the tape into the room 3 phone. Then return to room 1 and dial 2592 (which you got from calling Phi and Alice as explained above).
You will hear a pre-recorded message that explains how to find the correct code, which is 2652. Enter this into the room 1 phone to open the cassette lid. Take out the small pin.
Put the correct pattern into the room 4 desk to get the code 3472. Use this code on the room 4 locker to get a toy coin.
Go around to each room and lower the bed. Each bed has an outline of a person, and there is a ripped part that is circled. Make a note of which parts of the body are circled:
room 1: upper left leg
room 2: left forearm
room 3: upper right arm
room 4: right lower leg
Now go into room 4 and use the toy coin on the poster. Scratch off the areas that are marked on the beds.
room 1: upper left leg = 8 diamond
room 2: left forearm = 1 circle
room 3: upper right arm = 6 star
room 4: right lower leg = 9 triangle
Go into room 1 and use the aluminum foil on the desk that matches up with the patterns. The order is Circle, Star, Diamond, Triangle. Notice that the triangle on the girl's leg was pointing down, but on the desk pattern, it's pointing up. That's a 6, which implies that the 6 in the star is also upside-down, so the star is a 9.
Get the Secret File Password
To get the secret file, use the metal pin on the locker in room 1, then type in the password 9861. This is the number that you get from looking at the escape password upside-down.
Get the Escape Password
To get the escape password, look at the numbers on the girl poster. Since the triangle on the girl's leg was pointing down, but it's pointing up on the aluminum foil, use 6 as the last number. You should also flip over the star's 6 to get 9 in the second spot. The entire code is 1986. Use the metal pin on the room 1 locker, then enter 1986 to get the green password.
After the Escape
After the lounge, you eventually have to play the Ambidex Game. You and Phi go into an Ambidex Room together because you are a pair, and you have to vote against Tenmyouji, who is the solo who went with you.
