Stating it was "incredibly fun, deceptively deep, and always entertaining", he praised the gameplay, but criticized the lack of online features or downloadable maps.

He called the graphics "straight off of the Sega Saturn playlist", but "classic looking", and commended the "sweet looking character models".
