Huff...okay, this is the first one that kinda presses my buttons. The puzzles are nice and simple, and the end-of-area pics are solid. I was kinda curious if anything interesting happened if I *did* get caught, but that's just me. :P
I think the puzzle concept would need a little something extra to really make it shine in a larger game, but for a smallish game, it doesn't wear out its welcome before the end.
