As far as I'm aware Ko-Fi is generally against NSFW stuff being hosted on-site, so that might be a non-starter. I'll look in to other places, though!
Fair enough. I know about it being an option because of an artist I follow has published their game on there along with some bonus stuff. Spicydoesart I think that's their handle over on twitter. But yeah... I can't think of any other platforms outside of Itch that would permit this outside of the game itself being behind a paywall on your website or whatever. Especially since I think this year a lot of platforms across the web have been cracking down on NSFW games and art in general. Best of luck to you, I hope to give the game a proper go soon. Merry Christmas.
