Collect all cheese as fast as possible. Collect bonus letters to warp to an alternate dimension of huge cheeses (after you collect all normal cheese). Collect all 7 for a chance at a huge bonus. Eating cheese and cheese crumbs adds to your score and adds time to your timer.
Apples give you a temporary speed boost.
Balls have multiple functions, and can reveal secrets as well.
Some walls in the game are false... there are many hidden shortcuts around the maze!
