Someone just found a way to make me find A Capella very compelling.
The other day I mentioned there is a JS implementation of Super Mario brothers. I also mentioned that the physics feel about right compared to the real game.
Apparently someone did some analysis on the series and correctly concluded that the gravity physics are totally not realistic (shocking). The real nuggets are that he can jump 5 times his body height and should be unconscious on the way down since his falls achieve 9.31 g, which should render a human unconscious without a G-Suit. Maybe those are special overalls after all.
<canvas/>, though I think the one above is more like the original game.
