This game is fun, but it has a serious issue with crashing/booting you out of the game. This wouldn't be such a problem if it saved your progress if you were playing a stage, but it makes you start from the beginning, and occasionally will set you back so you have to complete previously finished levels. In the 16 hours I've had the game, this has happened 5-10 times. I'm willing to come back if this is fixed, though.
