most of the frames are actually in sotn. or rather, they're in the sprite set, they just never actually appear during gameplay. i only tweaked them a lil bit. it was interesting for me because i was trying to recreate what i thought his lil spinny kick might have looked like if it was implemented in the game. whatever the designers had in mind probably doesn't even vaguely resemble what i did.
but i still think it looks neat.
