I gotta say, this is one of the best I've seen out there. It's got CRAZY 1337 cutscenes. They aren't sprites, but rather CG art! There are even in game cutscenes that keep the plot rolling. The gamplay is smooth too. It's nothing without the occasional stickiness that even the best can't get rid of, but its pretty smooth nonetheless. You can do the double-jump attack from Sonic 2, as well as spin dash of course. What's really awesome is that the game has an awesome interactive environment. You're bashing through walls and jumping on bounces all the time, and it even has swing-poles like from Sonic 3! It's good stuff I'm telling you
