"Outsiders" Is a romantic-comedy (+18) visual novel project made by Midwest Games.
Your game is nsfw by your own description.
I do not know the policy for demo versions of nsfw games. But you promise nsfw content along the road.
Maybe you would want to release two versions of the game. Or one sfw version and a separate nsfw dlc/patch. Then you could claim, that you have a demo version of a sfw game. But currently, you have a demo version of a nsfw game.
Or put it another way, would accounts that chose not to or are not allowed to see nsfw works be your target audience? I think not.
