probably not in the specific case of sprites, because animating those is a lot of work! you're going to need a pretty big asset budget & team, and i think most FVN devs just have to prioritize the essentials.

also, ren'py is not particularly good at doing animation. realizing i could animate backgrounds & cutscenes in Godot's pretty convenient visual editor with my own engine made me want to experiment with those, though, so watch this space for future developments
