Things to improve:
1. back of the jogging sprite, it looks like the vanilla sonic walk, and not like what it looks like at other angles.
2. i know i said this in my last review and i dont want to pester about it too much, but i think the running animation should be the jogging animation. the running animation was changed to the peelout sprites, but i dont think it fits all that much. if you do consider this, PLEASE fix the thing i mentioned in the first reason.
3. sprites look a little off. idk how to explain it but it might be the shading as some other people have pointed out.
that's my review and if you see this, please consider some of these. especially the first one!
