Very nice, just needs polishing.
It's just a few glitches or irregularities that bug me. If you use the regular sword, then you end up swinging at an enemy and sliding halfway across the arena and then you can't turn around, and then you get hacked to death by the baddies. Also, it takes a ridiculously long time to stand up after being knocked down. Finally, the suicide guys obviously are intended to be dispatched with the gun, because you get injured at close range, however they have an extremely large amount of health that makes the game really tedious.
However, menu design is excellent. Although the enemies get a little old, they are fun to kill. If you made a sequel with Devil May Cry level depth, instead of the same old arena of baddies, that would be excellent and I would play it all day.
