Super Mario World: Super Mario Advance 2 boasts all 96 levels from the original Super NES game, from cheery Yoshi's Island through the sprawling Vanilla Dome to the grueling Star Road. While some levels emphasize pure action, others require you to puzzle your way out of the mazes and illusions. If you find the hidden key in Star World, you'll gain access to the extremely challenging Special World, which has its own hidden secrets.
