It evolved from the concept of just a creepy weird town with all the residents being secretly monsters and it followed an emotionless 8-year old girl. I remembered having no adult show their face as a style choice. All coming from a joke about "what the hell was wrong with this place".
It changed alot from there the characters are now 13, the every resident being monster point was eventually dropped, though it did had lasting effects on my human character designs. And my characters personalities were either tone down (hila, F) or just changed completely (Mc)
