I believe there is a way to report it to Norton as a false positive But I'm not sure how. It is fine downloading it and extracting it (even did a file insight and Norton said "seems legit") but actually attempting to start it triggers Norton to quarantine it.
Does this mean you can't play the game? If that's so, follow this guide: https://smallbusiness.chron.com/make-norton-permanently-ignore-file-68725.html. This makes it so Norton ignores specific files from scanning. If this guide doesn't work, try to google other guides to make Norton ignore specific files and folders.
I don't think Norton is going take a lone indie hentai game developer too seriously (just a hunch lol). Follow the guide and let me know if you can run the game.
