If you start a game in english, switch your iOS language to french and resume your game, the game will be stuck in french even if you switch your iOS preference back to english!
I had to uinstall and reinstall the game.
Also its very laggy on iPad (3rd gen), I would recommand an option to disable the retina display to improve the performance like touchgrind BMX.
