Original concept. It was really fun to play, which makes it a bit frustrating that there is "only" a few levels. Visuals, sounds and UI are good as well. I have just a minor complain (that will probably be difficult to fix) with the "Hell world" because since its layout changes a lot compared to the "Paradise world", I always had to fail a few times just to know what the level asks me to do.
Good job anyway :).
