Im playing this game on an iPhone 4, which can have iOS 7 on it. Id like to think of it that you have been able to update the app so that the game is more compatible on newer iOS devices. However, the negative effect is that when this phone updated to this version of the game (as of this writing), it is SO SLOW. Now granted, Im not using this phone as my main phone (I have a 5S), but I have this phone around, as some sort of gaming device that I can pull out at any time, even if I cant play newer games on it. With that said, would it be in your best interest if you could optimize the game so that it would run as it used to, VERY WELL, on this iPhone model?
