yea usually the animation is not too heavy in these games just some minor sprite animations and like arm swinging for the bosses etc. player movement leg swinging and like leaning and just mirror it. the spin part is not very imaginative its just the funny wheel that gives u buffs and debuffs (mostly debuffs). mostly just wanted to work on this type of game.
realistically the debuffs from the wheel is wayyy overkill for this difficulty though, but i feel it would have been mostly fine in a lesser difficulty. i made the tools to add an easier mode in a day or so, but had some issues porting it to webgl and missing features on the last couple of days which cost me most of my time sadly.
