That might lead me a bit long answer but to be shortest,
Itch.io no longer be able to show 'paid NSFW games' in there site in order to avoid credit card company(Visa, Mastercard)'s restraint.
And all the paid NSFW game dev including me should upload a new page with demo game.
The paid page for the game was able to search in the Itch.io by tag or just directly by it's name before but since it's not anymore, we just made a new free demo page.
