Superguy and Megaboy

About

Superguy and Megaboy is a high-speed, free-roam platformer that is somewhere between 2.5D and 3D. Players can attack only on a 2D axis but otherwise move freely in 3D. Attacks will only hit their targets if they are positioned at roughly the same 3D depth.. meaning if you see a bad guy in the distant background, you won't be able to hit him (or vice versa) unless you move up close!
