Really fun game! I'd recommend anyone reading this to play the downloadable version if they can. The 3D visuals are fantastic and really add to the experience.
What slightly bugged me was how the music kept going at an uneven tempo in the second part based on how you move, since I kept dying and couldn't listen to the next part of the song. It's a decent incentive to beat the game, though. Music's good. Is there a way to listen to the second track on its own, at an even tempo?
