This is exactly what I was afraid of when the NSFW games purge started. I knew it wouldn't be limited to just smutty content and knew it would move to general adult content in games.
But mouthwashing isn't NSFW, at most those upcoming console ports would be rated M for mature. Not adults only.
Edit: I recently found out why mouthwashing wasn't indexed, now I'm confused as to why the devs would go out of their way to make an itch page, only for it to just link to the steam page?
