A mode with platforming stages and battles against opponents, featuring unique storylines for each character. There are 12 platforming stages (2 optional) and 5 versus battles. Within the stages are different collectables, which unlock character costumes, selectable music, or extra info and tips in the "Extras" and "How To Play" sections. Additionally, completing the story for a character unlocks an additional outfit.
Smack the Crystals
A mode where players try to pop all of the crystals in a stage as fast as possible. Each difficulty option is a separate stage, but the stages are the same for each character. This mode is also used in Arcade Mode, match 8.
The standard mode for playing matches with other players or CPUs. The time limit and life count can be changed in the options menu.
A mode in which players knock around a ball (and each other), trying to hit it into the opponents' net. Every time the ball is hit, the amount of points gained when scoring increases. However, once the ball touches the ground, it resets back to 0.
