Watch the little beginning part then click start to begin. Choose either mario or luigi by clicking on them. It is a scroller. This is only version 1 so the enemy or enemies are not very complicated or programmed. use arrow keys to scroll along, spacebar to "fire" a fireball and up arrow to jump. Do not jump on the enemy I haven't programmed jumping as an attack yet. Please download and remix this or offer advice. I have tried to put in secrets and coins and stars, but you can put in whatever you want. I have no idea when the next version will come out. Enjoy.
