A common reason for frequent crashes in the game is the low amount of memory (RAM) available. Apart from crashes, it can also cause the game to run and load slower. Our suggestion is to stop any processes running in the background while playing the game, and to restart your device regularly. If you're still having trouble, please contact our customer support service by clicking on the "Contact" button found in the settings menu (the settings button is in the lower right corner) and choosing the "Contact Us" button in the upper right corner of the screen. You can also find us on our support email "support@nanobitsoftware.com".
