Crashes, weak story

Sound doesnt work with iOS 9, causes the system to crash. I was able to play all the way through by muting all sound fx and voice. Beyond that, the game was short and the story kinda weak. Up to 60 levels, but you only need to be level 28 to beat the game? Never had to use the gene talents except to heal - why include that component and not utilize? Odd.
