Lets put this in perspective...

Ive had the game since mid July. I love it. Of course it has bugs and glitches. Ive had an iPhone since 2009. Downloaded 100s of apps. I cant name one that never crashed (at least once) and/or had a bug of some sort. None are 100% perfect; not even Apples. With that said, this game is truly one of a kind and doesnt deserve a 1-★ rating because you arent good at it or because it crashes on your phone (maybe youre running too many apps, simultaneously).
