There was another game with a premise similar to this where you become a witches familiar. Last I recall, it was abandoned, and I can't even remember the name of it to check, but I do recall enjoying it. I'm glad to see someone else making a game in a similar vein.
Witch's Familiar was actually an inspiration for Familiarity. Premise really spoke to me, so I wanted to make my own take on it. (With an emphasis on cuteness and happy family moments.)
Though with the way my health is getting in the way of writing, I may have to hope that I just manage to inspire others instead. The rest of chapter 2 was supposed to be done already.
