Mario re-invented
Which isn't exactly a good thing. But not a bad either. add music, goofy backgrounds, and as I believe someone has already said, new obstacles, maybe even powerups etc. And you have a valid Mario clone in the making :) Which is good for those who like Mario, but may be just as boring as this to those who does not.
Anyway, make a better one next time, and if you add music and bg's, which is easy, ppl might even become a slight bit addicted XD
