Meant to get this up hours ago, but youtube worked against me in its processing. Oh well. Great game, definitely worth the $1 on XBL. Kinda lax commentary, but the visuals should be enough, then again that might end up being my style. Let me know if I should be more exuberant.

This was actually the first game I downloaded from the marketplace. The music alone is worth the dollar. They definitely need to implement online coop though. And there aren't unlimited lives when you play coop.
Yeah, unfortunately I don't see them expanding it at all since it came out a while ago, maybe a sequel... but I think that might ruin the charm of the original.
