I just played the game for over an hour with a buddy of mine. So much fun!!! We played a couple times on co-op mode, but still weren't able to reach the wizard mode.
I still have never seen the guillotine mech in action on my game. When exactly does it come into play? We nailed a couple guillotine shots during the "Alice" mode, but it never grabbed the ball. Do you have to beat the mode?
