Freezes and resets to beginning – X2 Blocks : 2048 Number Puzzle Review

I like this game a lot. However, it freezes whenever I get into the high levels (into the “c’s”), and the only way to play again is to restart my iPad. The game then goes back to the beginning level. Very frustrating. I will delete this game even though it is fun and challenging when it works properly.
