Hey, I get what you’re aiming for. Games like MGS3 and Undertale don’t stick because of hype they stick because everything lines up: art, pacing, tone, and restraint.
Right now what you are missing is a visual backbone. Without backgrounds and a locked look, RPGs tend to spin really bad. I’ve seen that happen way too many times.
Quick questions tho
Do you have any visual refs at all, or is the art style still mostly in your head
Are you aiming for a short, finished story first, or a bigger long-term RPG?
