The Super Mario Galaxy and Super Meat Boy franchises have come together. Developer Aubrey Hesselgren (who goes by Hilarious Cow on Twitter) has released a video of a "completely unofficial 3D version" of Super Meat Boy called Super Meat Boy Galaxy.
Hesselgren created the Mario/Meat Boy mashup for Team Meat developer Tommy Refenes' birthday. He used Unity and Blender to create the game, which meshes the worlds of Super Mario Galaxy with the blood-soaked jumping of Super Meat Boy.
Hesselgren said Super Meat Boy Galaxy is not much more than a "training exercise," and that it is not planned for a wider, public release.
