Slight improvement on an already great animation
I couldn't see anything different to start with, apart from the title screen. Then you got to the fight scene and there was extra blur. Did you also add some sound effects? Yeah, I think it did improve on the original a small amount, but whether it was worth a weekend or not is up to you.
Reguardless of any changes I still love this animation and its one of the highest quality I've seen on Newgrounds. There's a couple of things I'm not so sure about (the ending music, the 'cast of characters'), but loads more I think are great (the art, the main music, the fantastic animation, the feel of the piece) and besides those are personal preferences anyway. I really hope the portal sees more from you
