It's a fun puzzle game, original as far as I can tell - never played anything quite like it. It shakes a bit back and forth when pushing blocks or keys (or bumping into walls) and that gets a bit annoying. Turning is fluid but moving up and down is quantized and you can occasionally push a key or black in such a way that the puzzle can't be solved - but there's a rest button so it's not a big problem. Graphics could be more diverse and interesting, but that's not the most important thing in these kind of games.
