Gameplay.
The game is based off of Super Mario Bros., with every of its 32 levels. The player controls Mario (or Luigi, found in an easter egg) to fight 34 other players. Defeating an enemy would cause it to go on someone else's screen. Most of them are defeated by stepping on them. If a player is the last Mario alive, then they win.
