Most crappy controls of any game I have ever played. The concept is good, and soemtimes, when you finish one of the puzzles, you get that sense of accomplishment, it just is hard as hell. Not because you need to think. It is hard because you would have set yourself up a very awesome path and are sure to win the game, when suddenly, for no reason whatsoever, the camera changes and your character walks off a cliff. It is really annoying.
