Thanks for your time and feedback!
It sounds like quite a few people liked the aesthetic. I found it by pure accident while aiming for a different aesthetic, but when I hit this aesthetic I realized it fit the cool factor and simple-enough factor. I definitely will try making future games using it. Maybe eventually I could have players associate that aesthetic with a subset of my games like a brand.
Replacing the player character with a cute-stylized character sounds like a great idea. I'll keep it in mind for future games how the player characters should help focus the game's messaging.
Part of the aesthetic came from me trying to deal with my lack of pixel art skill. PS1/2 3d models seem to rely a lot on pixel art for their texturing. I'm really looking forward to your pixel art master class.
Good point about simple mechanics making the game fun too!
