Serious performance issues

I cant get past round 5 without the game going 2 frames per second or crashing. It even sometimes does this while o. The home screen. Also, after battles the 30 second, unskippable ads are really annoying. I usually dont mind ads, but that is just ridiculous. Fix the performance first, then I will enjoy it.
