Update 15

You inspect all the doors. The only door that is unlocked is the heart door. All the other doors have locks on them except for the square door, which has a keypad on it instead. You may be imagining things, but you think you heard noises from behind the square door as well.

You go through the heart door.

This room has a computer in it. There is also a missing poster on the wall.

What will you do now?
