Stirring animation will be great! Suggestions? This is already so perfect! I only have one little extra idea, which is to have some sparkles, just a transparent sprite that could be layered on top of the potions in some cases maybe. To make "extra magical versions" of the potions, or maybe for a little potion finished anim in the UI. Not sure, depends on what you think ofc :p
Anyway, thank you for making such great assets!
