Need more characters!!!
This game is so addictive. I stayed up all night playing. The hardest character is Tankman... that level against Salad Fingers and Alien Hominid was nearly impossible.
Needs more characters. You should have a clock fruit, perhaps the clown with the penis, swear bear, wink, Scrooge McDuck...
Too many characters on newgrounds to be limited to just these.
Oh, and perhaps you should make some sort of stand-alone version that isn't flash, so when you go to places (school/work) that block newgrounds, you can keep the game. I put the flash file on my iPod, but when I go to other computers, the stats go away. It would be awesome if you found a way to put it on cell phones (cough).
