The site is in no way focused on children. The most prominent games here, consistently, are horror games.
Viewing post in Itch.io getting rid of NSFW games is amazing
That's downright contradictory, considering that you said you prefer games with only a "little bit" of blood and gore.
Are you retracting your statement to now be fine with things such as: kidnapping, murder, profanity, religious horror, torture, eldritch horror, slashers and more? If so, there's no reason at all to say you want 18+/NSFW/adult games removed. Which is something I would be incredibly grateful for you understanding.
