Same thing with me. I modified my game 5 times and every time it gets rejected. As akhelys said, it's like they don't even review the app/game and reject it automatically. Upon sending a comment requesting the motive of the rejection, they send an automated response and than they stop responding. I appealed and they still have to respond. Very unprofessional. I might as well publish my game on the Google Play Store and forget about App Store for good.
