Currently, our development team's main focus is to make the game as stable as possible.

There are a few steps that may help you with this issue:
1. Make sure that your internet connection is stable; resetting your router sometimes helps.
2. Disable other non-essential apps running in the background on your device before starting the game. The more processing power your device has, the better.
3. Reinstall the app – before doing so, please make sure that your progress is saved on Google Play or Game Center.
