I like the bouncy-ness of it but I feel like the jumping frames should create a speed similar to the falling animation. Like having the jump be faster, slow down at the max height and then speed down again.

Sure, I can do that. Just gimme a moment Done.

I knew you'd have a good reason. Of course a little more outer white space would make the sprite a better read in both the art and the preview.

He's a rather bouncy and hyper fellow for just some mindless slime, eh? 

Because the programme I use to animate stuff doesn't seem to allow transparency, and I guess because it looks better on a light background.

Why the BG?

That remnant slime is quite playful.
