Itch deindexed all adult games and not indexed new one. This message pops up until itch checked the game file and with their new policy they probably never will. I'm not happy with this situation either.
Run your antivirus software on the archive you download and run the game on your own risk - like with everything you download from the internet. It's not my first game and I'm a good friend with my playerbase - I'm not planning to ruin my reputation by scamming.
