I think that overall appropriate metadata is what carries games on itch.
I find that tagging general genres doesn’t really do too much, but ones that fit your niche do super well. Most of my first app’s traffic is from one tag and one of its accessibility features alone, and my second one is entirely made of the yuri tag, however it gets half the actual plays because it’s pretty clear it’s only really at the end of the game.
So I think people are generally searching for things that are similar to what they already enjoy, and I don’t know if having more tags dilutes your game’s visibility or not compared to just appealing more to a niche.
But I think in a case like this it never hurts to appropriately label input methods and accessibility since there’s a lot of people that rely on those features.
