So, I finally finished the ground melee sequence. It starts with a 1-2 punch followed by a slash which uses the spinning top bomb animation, but with a couple frames tweaked to move better, and then a tail attack which leads into the head spin. The spinning attack has been shortened down to 4 frames, and no longer uses the 2- and 8-frame versions interleaved into a 16-frame animation, since switching between the two like that would make for annoying code, putting them together in a single animation takes up space, and this looks faster and better, anyway. I got the idea from CBL's spinning attack, which looks really nice.
EDIT:
I made a Minecraft skin.
