RPS reader (not making this up) Fuggles the Lightfuggly One sends word that PETA, aka People for the Ethical Treatment of Animals, has published a parody of Super Meat Boy. You can play Super Tofu Boy here. Is it still a parody if it's just kind of... Super Meat Boy, again? There's not much ridicule going on here, except for Bandage Girl two-timing Meat Boy. But you know, I always suspected she was bad news.
Which brings us to an interesting point. While Super Tofu Boy is a hundred miles away from the 24 carat running and jumping of SMB, it does use the same running and walljumping mechanics. For a quick & dirty look at the mechanics of Super Meat Boy, Super Tofu Boy can provide.
EDIT: Brave RPS commenter Terry points out that you could just play the Flash version of Meat Boy. So, I suppose this doesn't need to exist after all.
