Up Arrow - Jump Left/Right Arrow - Walk Down Arrow - Duck X - Run If Mario is stuck on a wall, unable to move, or stuck in a crawling pipe, press the R button to reset Mario's position, that should fix the problem. If there is anything that pops out where it doesn't belong, click the green flag twice. If that doesn't work, please comment down what's wrong. If the game seems slow or Mario is walking slow, just jump it will resume its normal pace. If you see Mario turn into a black box in and out, this means you've left him standing too long, just restart the game by clicking the green flag. This is my first platformer. I hope you enjoy it. :)
