I'm thinking Satanic Hope and Despair - I want to make a solo game about being a medieval peasant sent to purgatory who is trying to get to Heaven and avoid being dragged to hell. 

I also had an idea for Satanic Jelousy as a comedy game about devils trying to steal each others soul contracts, which I might make as a one-page game if I have extra time!

I've wound up going with a Satanic Feelings as a whole; sort of based on Mindfulness.

That said I am wrapping it up like a magical girl anime but one of those one written by people that grew up in the 90's like Machi Maho so a lot of adult themes wrapped up all cutesy so I guess I'm also taking inspiration from Maids the RPG?
