Kirby's Dream Land Remake Project [open to anyone]

It's not fast enough!
While you have fluid motion, the frame delay should not be constant.
Really I think you could remove the second frame, and make the third one go lower. Then, have the last one be a recoil, or return back.
Generally a fast action has 3 parts:
Build up --> Blur/Hit --> Recoil
Right now you don't have any sort of recoil, and the hit part is too slow, so you lose impact.

Take a look at this version from KniD. Look at the impact!
