The VG Resource

here's a suggestion from your friendly neighborhood gors

Yeah, the animation kept bugging me the more I looked at it. Thank you guys for your help and advice! I liked your suggestion alot, Gors. So I went with it. Made better animation smears from another suggestion, and made a squash effect for the fists on impact.

I think it's alot better now.

that shake feels more like bouncy jelly than like something heavy just dropped, I think

This thread on pixelation, starting with this post, should be quite insightful for your animations
I'll look at your animation in the meantime, to try and see how you could edit it.

Edit:

I changed the outside of the shoulders/arms, but you'll have to do the same to other muscle groups. Remember that they're bits of flesh hanging from a frame.
Made a few changes to the frame delays, too.

I hope these help!
