(If you've played Super Mario Brothers on the NES, you should know how this works, but in case you haven't...) INSTRUCTIONS: Use the left/right arrows to move, up arrow to jump and X to dash. Jump on Goombas to defeat them, collect mushrooms to turn into super Mario. Lose all of your lives and it's game over! Just like the original, you can run over small gaps, collect coins and play until you run out of lives. (Or you beat the game.)
