i got the app Tap Tap Revenge 2 awhile ago but recently started playing it but im having problems with it. when i first open it will be perfectly fine but after a few songs it will start to get really slow then it will either crash or my iPod will just freeze. when it freezes i have to do a force shutdown (hold the home and sleep buttons) and i know that doing that is bad for my iPod. does anyone else have this problem or does anyone know how to fix this problem? i was thinkin that maybe cuz its newer there is still some bugs being worked out but im not sure. please help me
