This idea definitely has potential! However, I couldn't really figure out how to finish the level. I gave each guard their respective item, but the elevator didn't unlock. Also maybe I gave the wrong guards the wrong things; I couldn't figure out who the bathroom guard was, nor who the classroom guard was.
Something that could definitely be improved upon is, if you've bribed a guard, they shouldn't still send you back to the start.
However, I really do like the concept!
