The device is crashing? I've just deleted the game from my device and side-loaded the build from here and I don't see a crash when the game ends, even after several attempts. Do you have any more information? The game doesn't have levels so I'm not sure where its happening for you, but I assume when a game ends.
Pinged you on Twitter, too. If you can take a video of whats happening (if that's easier) you can send it to me at scenicroutegames@gmail.com
