ooo nice animations. Nice to see some character in a simple slime. Some critiques:
Hit: I think have the slime squash down 1 or 2 pixels again at the end before returning to normal. Itll make him like more jelly like. Think of like dropping a ball, its gonna do alot of really small bounces at the end before coming to rest, not just a few big bounces.
jump: have him squish a little more when he hits the ground
dodge: something about the timing is too even; doesnt make him look stretchy. He needs to stretch slowly, slowing down at the end of the stretch as hes being stretched to his limit, then snap back quickly. Something like that I think, Im not an expert.
idle: same issue as the Hit animation, have him do another smaller bounce.
Wow, beautiful! Real good animations
