Good game but keeps crashing

I liked the game itself fine and didnt have any issues with the scenes. However, when I was about 2/3rds of the way through my iPad froze then booted me out of the game. When I went back in it had completely reset my progress and I was back to the very beginning. I uninstalled and reinstalled and played without major problems. I got partway through the bonus game and called it a night. When I went to finish the bonus game I found the game had reset itself again to the very beginning! Deleted. Maybe Ill try it again at some point but right now Im too annoyed.
