Thanks for understanding! Unfortunately, itch.io recently deindexed all NSFW games, so at least for now there’s no way for me to offer payments through itch.io.
If new platforms appear in the future where NSFW games can reach players and be sold easily, I’ll definitely be there.
By the way, what would you think if I offered a standalone version of the game on Patreon with more affordable one time purchase of the latest version (without future updates included)? Would options like that be interesting?
