The issue is that we get the subscriber content warning every single time, which can make people think that the pack does not work and quit right there.
If the bonus pack is detected, you should remove the subscriber content warning.
Some advice. To increase your chances of passing GOG's curation, you (or the users) should create a GOG Dreamlist page. However to create a GOG Dreamlist page, your game must first exist on IGDB.com. So please create an entry on IGDB, so it could then sync with GOG's Dreamlist, so we could create a page and vote for the game.
Oh my what a gem! I'm so glad I found this. Instant purchase. So many different fetishes are present.
You should REALLY consider publishing this on GOG. There are a handful of NSFW games on GOG that were otherwise banned on Steam. That way we won't have to deal with the size limitations of itch and you'll get more exposure. I'd rebuy this gem on GOG instantly.
