SUPER MARIO BRO-OP
Mario and Luigi have defeated Wario but now the brothers face an even bigger challenge… or at least a taller one: Waluigi! 
Can Mario and Luigi make it through the mazes and hurdles to save the kingdoms? Probably!
∙ Two Player Co-Op
∙ New graphics, levels and music
∙ Unlimited lives
∙ No 1-up mushrooms
∙ [!]-box removes lifts
∙ 20 coins = Star power
∙ Additional stars in invincible boxes.

Navigate through maze-like levels in The Mushroom Kingdom and Sarasaland. 
A lot of times you need to hit the boxes with dotted lines to make progress.

The game is made with two player co-op in mind but the game is beatable in single player mode, 
although there may be some paths that are tricky to reach without a second player.

This game features two player co-op, updated graphics and each world has it’s own overworld music.
