Goes out of the game

This game is my favorite game but then it started to just get out of the game while I was playing, it would go back to the home screen and I would have to do it ALL OVER again!!! and it got annoying so I tried to delete the game and get it again and it STILL DID IT AGAIN!!!!!! So I finally just deleted it..

LOVE YOUTUBE ??? about Bounzy!, v2.5.1
