Super Mario Bros. 3 is an action platformer game for the Nintendo Entertainment System.

This game is inspired by the flash game Infinite Mario Bros. Most of the levels are designed based on the levels of the flash game. Yes there are a few custom levels in there, but the concept is all based on the flash game. Each world has 4 levels and up to 6 or 7 levels in World 6. Also, a first for an SMB3 mod: the order of the Koopalings are switched and are faced in a different order rather than traditional order.

Version 1.1 update:
Maps were altered a bit especially World 3 and that glitch was fixed. All worlds now end in a fortress stage thus some levels had to be moved around. Wendy and Lemmy's boss rooms were switched and the Mushroom House, W7-3 and W8-3's chest now contains a fire flower instead of a mushroom.
