As of version 1.1.1, we are not currently aware of any specific crash bugs. However, if your device uses the ART runtime, it can cause crashes at random times in the game, especially at start up. Please switch to using the Dalvik runtime instead of ART to solve this problem.
If you are using the Dalvik runtime or are unsure of which runtime you are using, and are still experiencing a crash, please email us at support@bitbybitstudios.com, or open a new support ticket using the button at the top right area of this page, and we will do our best to help fix the problem.
