Sonic the Hedgehog HD! Should hopefully be fairly self explanatory to more experienced users, but act 1 is the only playable level. This engine also has an alternating terrain system that allows Sonic to effortlessly blast through loops, includes bouncy springs with an easily replicated object placement code and a whole bunch of crystal clear vector-drawn sprites to bring the blue blur to life. Have fun and be creative, and of course thank tomicool for providing the physics and controls. Love to stick around, but I've gotta go. Fast.
