yes you are right there is a setting for "Show content marked as adult in search & browse" when logged in
but itch.io is strange, when not logged in , going through "browse games" on the main page and then in the "select a tag" in the drop down menu there is "adult" selection and it shows some games that are considered adult, and they show warning when trying to play them, but are still accessible , need to "investigate" more >_>; , just noticed now it shows some of your games, but selecting "bara" doesn't show anything very strange
anyway sorry for bothering , and thank you for the reply :)
your game is awesome
