it was a good, mind-bending game (especially for people like me who are horrible at puzzles in the first place.) But I found out that it's possible to shake the creatures off of a block. I don't if you meant to do that, or it's some kind of physics thing you forgot to erase while making the game, but it kind of ruined. Sometimes it made the puzzle easier than it should be, sometimes it made the puzzle impossible, and you had to restart the level. Other than that, it was a really good game.
