I've heard steam is doing this a lot, and what's more annoying is they normally refuse to look into it any further if they come to that conclusion.
I'm assuming they came to that conclusion because of the scene where Margret was at school with the MC, unfortunately steam doesn't care if its college or just school themed with adults they refuse to have any depictions of a school in nsfw games on their store, which i get but even if you choose to alter the scene or remove it out right they wont change their mind.
Its a crappy situation but i hope you're able to sort something out, i was looking forward to the release of this game.
It's because of the card companies they need to stop being cry babies since gamers will buy any visual novels if the story is good, the concept is good, and art is good because the companies aren't making the games it's the indie, but the card companies are fine with AI art those fuckers.
I believe people should draw whatever content and have the rights to sell it on steam.
Card Companies shouldn't have the right to blackmail what we can't buy on steam that's the whole point buying with a card. Unless we are buying real illegal porn that isn't two drawing fucking each other.
