Cool game ! Can't believe you made three genres in a week. Very impressive. I enjoyed playing each room, although I think adding a background music to each room would make it even more fun. Some things I'd like to suggest are putting the trigger for the FPS room at the entrance to avoid confusion, and adding some more feedback especially when getting shot (something like giving a red indicator in the direction you're getting shot from). 

Looks good but i couldnt figure out what to do in the fps room, sounds like i should have a weapon and be shooting but it ws just an empty room with walls like a maze.
