I absolutely love this game and everything about it. But whenever I play it crashes every minute to 2 minutes which is irritating because I just wanna play.

Response from developer

Thank you for loving the game, and sorry the crashes ruined the experience. Version 3.4 includes major stability and performance fixes for this kind of frequent crash. Please update to 3.4 and try again. If it feels stable now, we would be grateful if you update your rating.
