Freezes :( – Run and Bun Review

I just got this for my ipad because I'd been playing and loving it on my phone for months, and it's very high quality and I'm loving it to bits, but the only problem is it will freeze the screen in the middle of the run and cause your character to die because you can't see where the obstacles are. Has happened on multiple stages. Please fix!
