Graphics: This is Krinkles doing the art, so it is faithful, but I always thought Krinkles' own art was rather stiff(Mainly the weird ass feet and legs) when It came to the characters. The new graphics don't blend well at all with the old ones. (save for new clothes)
Audio:Average as always with madness works.
Game play: This is the games strong point. The game play has great flow and is fast pasted. But the idea of buying guns works against the in game tactic of "if gun ammo = 0, action throw gun" that is a REQUIREMENT until you get the ability to have a second weapon and/or the gun melee ability. And in arena it is nearly impossible to not spend the first 10 minutes getting killed over and over again.
Overall: Graphics are good, audio is uninteresting and average, single player is great, arena is bad.
