This is a wicked fun mario game. You have to beat up the baddies with a wide array of moves including the uber cool special power attack which will clear the whole screen in the event of an emergency. Combo attack the enemies with the Attack button (Z) to build up power and keep them at bay. When you have enough power, you can do special moves like Fire Fist and Deadly Jump. If the baddies reach the castle, you're done for.
