Some criticism
Loved the art, animation, and music. Can't find any fault to whoever did each of those. The game itself, though wasn't that great.
First of all, there should be other difficulties other than really easy and super hard. There were also some quirks I noticed in the game engine - Is there any real benefit to knockdown other than slowing down an enemy and making them invincible during those animations? Also, you can't turn around while jumping.
I don't know how many games the coder has made, but I'd like to see a bit more variety in attacks and specials. Like give each weapon a different fighting style and animation with it's own pro's and cons. Perhaps even a ranged weapon with ammo as an option.
Sorry it was mostly negative, but like I said, everything but the game itself is golden- It's why I gave up trying to learn flash, because I'd never be able to get coding and be stuck using public scripts I stole and messed with. and they wouldn't even work right themselves.
