The graphics are clean and crisp. While two dimensional, they are striking and it really looks like you are playing a cartoon, in high definition. The enemies are varied, the locations are interesting; you just don't get much better art direction than this. Boss fights are well done.
This review wouldn't be complete without mentioning some of the problems that have plagued the game's release. Many folks are unable to join a quick match game over XBLA. Some can't conenct at all. For such a high profile title, this is unexpected and should have been fixed. Also, the game is more expensive than the typical Arcade title, at $15. Personally, Co-Optimus thinks it's worth every penny, though some might disagree.
