In theory I should be able to get boob jiggle just with the sprites that are already being provided, though I have only looked into it briefly and skimmed some similar scripts people have released, so I might be being too optimistic.
I might find myself optimising it here or there to make life easier for myself, but tbh I'm pretty used to working with shit code anyway so I'll probably just use it as is, ultimately I'll just be messing around with it when I need a fun break. On the bright side the game isn't processor heavy, so even if the code isn't optimised nobody's going to notice on the player end.
