nice.

Agree with superian2, all he mentioned keeps here. You might do a Second Madness Animattion with the things he mentioned. Good Luck!

It needs some improvement like this:

1.Backgrounds,it will make it more awesome.
2.Feet,they not are flying,they are? (includes big feet).
3.ATP YELLOW BLOOD.
4.Better movements.
5.Better Play Button,with some more decoration

Thats all,good luck with your future projects.

P.D:if u will make a game someday i can be you beta tester ;) .

i gave this 2 stars because it has madness in it u need background

Pretty nice but i have a feeling you used frame by fram if i were you i would use tweens.
