Atari Anniversary Edition Cheats

Jump one hundred or more times in the front corner of the very first level. Losing a life doesn't break up your number of jumps. Now, clear the whole level of the gems and at the beginning of Level 2, a banner that says ''ATARI'' will appear.

In Level 5, get the hat and enter the door where Berthilda the witch is flying around. Destroy her and then go over to the corner where she was, and jump. The initials FXL will come up at the lower-right part of the screen. Those are the initials of one of Crystal Castles's designers, Franz Lanziger.
