Will this game at any point in the future be available to the public for no charge? And will there be NSFW and/or explicit content in this VN?
While Patrons will get earlier access, every build will be released publicly eventually including the final version too. Supporting via patreon or paying helps me pay for assets, which speeds up development but there’s never an obligation to pay!
as for NSFW, it’s a possibility but NSFW scenes need to be paid for and then drawn by the artist which pulls time and resources away from story CGs, backgrounds and sprites so it’s something that can be done depending on time and funding.
