This is impressive, but there’s a lot off about it. The speed Mario moves, how he jumps, the responsiveness—these things are all very, very important—and they’re not quite right. It’s open source, so I bet someone ail come along and fix these sooner or later.
If you want to see a Super Mario clone that seems like they got these things exactly right, check out Mari0. Mari0 isn’t a straight port. It’s a Mario-Portal crossover, but the little things were clearly painstakingly reproduced. It’s cross-platform and the source is available as well.
