So far I am really not liking this game; there are a lot of glitches. First off, there are some problems syncing achievements unlocked in-game with the Game Center; that is perhaps the most annoying. The second problem is that the screen sometimes becomes unresponsive so when you are doing a swipe combo to finish an enemy off, the game doesn't register your action and the enemy breaks free of your grab, making the game harder than it was originally intended. The third problem is that the game crashes somewhat frequently and is really annoying to go back to your last checkpoint especially if getting past enemies is made even more difficult by the aforementioned 2nd problem.
