WASD to move, SPACE to use the torch and E to enter a locker. Get past as many rooms as you can, avoid the entities that appear in the rooms. A-75: When you hear the sound, hide in a locker until it passes to the next room. A-???: When you see the stop sign, stop moving until it goes away. #-190: The same as A-60 but comes twice.
Thanks to Burgerriley for the original project Rooms.
