Broken Super Mario bros. It will seem normal at first, but as you go deeper into the levels, and do more things you would normally do in a Mario game... I suggest turn the sound up, as I've changed a lot of sound effects. Use the arrow keys to move left and right, as well as jump and duck (if you are big). Hold space to run and shoot fireballs (if you've read down to here, don't press space with a fire flower, or something bad might happen). O to skip a level and p to go back one. M to change the music, and H to get access to a few things to adjust to liven it up... even more. Have fun!
