I tried this a few months ago and hated the movement, but I tried it again because I wanted something short. And folks, the movement rocks actually, and racing out of a level is the best kind of fun stress. The bosses are a noticeable difficulty spike that made finishing levels obnoxious- I ended up cheating with debug mode to beat the final boss. But when this game hits you with a sick gimmick you have to figure out on the fly as you're racing at mach speed... that's some gaming right there.
