I actually love this game (the core gameplay is awesome and the controls work really well once you get used to them). In the last update they even lowered the price of the DLC to $0.99, which makes the full package an absolute steal. However, though the last update added facebook functionality, they totally broke the UI and menu system. When you finish any of the challenge menus, half the buttons dissapear completely making it impossible to navigate thorough the menus, and basically forcing a restart. In the present condition, the game is pretty close to unplayable. If youre thinking about a purchase, Id wait for the next update or youre just going to wind up frustrated and furious.
Namco, please fix, and in the future, test your updates before releasing them.
