Amazing
Newgrounds Rumble is, hands down, the BEST fighting game on Newgrounds, if not the best game period. The controls are fantastic, the animation is fluid, and the great unlockables keeps you coming back for more. Fantastic work, I hope to see more in the future.
On a personal note, Salad Fingers reminded me very much of Twelve from Street Fighter III. Not at all in a bad way, though; it fit the character perfectly. :]
