cool idea. giving the guards spotlights was a very good idea, so you can tell where they're looking. however, the time limit felt forced, so i'd suggest replacing that with some sort of lives system, like you can only get caught a certain number of times. also, the money felt cramped, it would have been better if it was more spread out. maybe the rooms could be procedurally generated?
it's a good game, and it's close to a great game. 5.5/10
