Earlier this year, a Super Mario clone named Super Bros! made its way into the App Store. Given the company's history of blocking and removing obvious Nintendo game ripoffs and emulators, it was surprising that such a game made it past the review team.
Eventually, though, someone at Apple caught on and Super Bros! was pulled from the App Store, but it didn't stay gone for long. The game returned today as "Pixel World!," with updated sounds and game assets that help tone down the whole "ripoff" vibe a bit.
