Great game but needs an update

This game is really good, but I had died and didnt click revive, then the game just crashes!!! I am really upset by this because there was no way to save data to the device, so if I want to play again I have to delete the game along with all of my data! This game needs an update soon because I dont wanna have to lose all my data. Please Fix This!
