Could be fun if it worked properly

The game itself looks nice enough, pretty close to the cart game of the traditional rival.
Game center seem stuck as it asks for the password again and again without managing to log in. Must choose "cancel" in the end.
No retina support, not even for the menus.
Much worse: on my retina MacBook Pro, the dock is stuck continually on, overlapping the game showing a frozen cursor.
Thats quite too bold for the asking price and no updates since launch, soon a half year.
