Almost amazing - I think the art, audio, theme, and gameplay were all top tier, however I get the feeling there might have been some framerate dependancy type thing - it felt like the game was running at 3x speed.
Although a lot of the attacks felt impossible to dodge, and keeping track of the player character was not an easy task, its obvious a lot of skill went into developing this and with good balance it might be my #1 entry, but the insane speed just makes it a super rough play experience for someone who doesn't often play this type of game.
Like I said though, so many areas felt really really well crafted and the game was still pretty enjoyable as a whole, even though it's fustraiting that I couldn't enjoy it as much as I feel like it deserves to be.
