press green flag until the "0" in the top left dissapears!!!! space to jump, down arrow to slide. similar to super mario run. (obviously, hence the name.) jump on goombas, hit question blocks. press "z" to throw fireballs. 1 fire flower gives you 2 fire balls the mario you get is random. it can be the old mario or the new. try click ing the green flag more to get a different mario!
