Hey SaltyRoo, I'll second Minoanon and say it's intentional, but I do see where you're coming from- even if the humans are supposed to look kinda mundane and unattractive to contrast with the supernatural beings (some like Nini are supposed to look kind of grotesque), it's possible that it's not properly conveyed and it comes across as an excuse for bad art. The newer sprites, I think, get a little closer to this idea, but some of the old NPCs (Greta, Ismael, the trucker from Luke's intro, etc.) could use a redraw. We included a question about this specifically in the end of build survey because it's criticism I've heard a bunch of times. When you're done with the build, let me know if the more recent sprites look alright and get this across.
That said, even if we do redraw her, I think the old Greta sprite is too iconic to completely remove- we might keep it in the speedrunner route.
