Like, severely bugged. Im using an iPad 1, and I can play the new Arcade levels without purchasing them by beating Pyramid, and then playing all levels after that without returning to the menu.
Also, in the new arcade levels two buttons appear on the screen that should only appear in multiplayer modes.
And also in the arcade levels, all enemies start with 66 HP instead of 100. Makes for easy Grenade and Gun killings.
