Sorry to hear that. I've been unable to replicate the issue. Does it crash the first time you try and select a level or does it work most times and only seem to crash after playing for a while?
I've released a new version of the game with an optimised level select screen. I'm hoping this will fix your issue, as I'm not seeing it on my device. But a lot of people have described issues with lag so I'm hoping this version will be a little smoother.
