Oh no, she's adorable
I'm not sure how I haven't checked this thread before now. This concept is very memorable, it's going to stay in my head probably until I go to sleep.
I'm already intrigued by the nasty bunny friend's bullying habits and am half-expecting the girl to overtake the eldritch being's throne by the end. I love that she's a cyclops.
I'm getting some Alice: Madness Returns meets Undertale vibes, which I promise is a compliment. You've mentioned that the general aesthetic will be childlike, which makes sense considering the premise -- I'm curious what plans you have the game's audio, if any.
