Super Mario Galaxy 2 is a pretty fantastic game. So it comes as no surprise that some enthuastic fans have taken it upon themselves to create even more levels for the game. The project is dubbed Super Mario Galaxy 2.5 and, should it reach completion, will offer some of the most challenging 3D Mario levels created thus far.
Right now, there's only one completed level, a hack of the original "Step to the Beat." Like its predecessor, the level features disappearing beat blocks. But, you'll need to utilize many Mario tricks to make it through alive, including the notorious Yoshi-jump.
