Super Mario Galaxies plays nothing like the real deal
While Mario is definitely in an outer space setting -- evidenced by the spacesuit and the speckled black background -- and appears to be shooting star bits, the similarities between Super Mario Galaxies and Super Mario Galaxy end there. You won't find any 3D platforming, planet hopping, or manta riding in this homebrew release. That might be a lot to expect from a single programmer, but when a game is titled Super Mario Galaxies, it sets our expectations pretty high.
Instead, Super Mario Galaxies is a simple shoot-em-up in which you dodge Bullet Bills and floating sprites that look like Care Bears riding Star Wars landspeeders. Knocking into the latter enemies decreases your life bar, but you can shoot star bits at them to put some numbers in your score. Running into one of the invincible Bullet Bills, however, gives you a Game Over.
The game is actually more fun than you'd expect, and we could see ourselves playing it pretty often if it had more depth; just don't expect it to be anything like Super Mario Galaxy.
