Let's see if we can defy gravity in part two! Gravity Man's stage is one of my favorites in the classic series. It was Super Mario Galaxy before Super Mario Galaxy. Anyways, the stage is filled with anti-gravity sections that reverse your center of gravity depending on which direction the arrow's pointing. The stage itself really is not that difficult, it is just gimmicky, but hey, that is what makes it so fun!

BOSS: Gravity Man
Gravity Man is a breeze. All he does is shoot his arm cannon and reverse the room's gravity. It should be worth noting that you two are always on opposite planes of gravity, so you have to hit him when the gravity switches. Your best bet is to throw the Star Crash at him when you switch. Once Gravity Man goes down, you'll get the Gravity Hold.
