What sort of genre will it be? I've just been trying to picture frotting with social commentary in every possible setting in my head. I like to imagine it as a Doom clone, where instead of a chainsaw you have a massive boner and the demons yell at you to stop rubbing dicks with them.
Oh, it does involves demons! :D
But in it you're a demon that's fighting hierarchy throught magical challenges. I suppose you could say it's a fighting game, but seen from above and where mostly dicks and hands move. I do admit the premise is a bit convoluted XD
Here's some gameplay preview with placeholder art ( very NSFW, of course)
