but idk how itchio is helping me to build a community
Itch is not doing such things. That's the point. For this to happen by merely existing on Itch you need a lot of luck and a very good game.
Do not expect wonders. Your game is very AI heavy and that's not popular. You are actually doing well. Could be worse, could be better.
As a side note please read this https://itch.io/t/2885012/tips-for-reducing-the-size-of-your-build Your game seems quite big for a version 0.2
why itchio doesn’t and just leave me at the bottom of the search.
You are at the top of search at #3 at the moment. But why would people search your game by name?
If you talk about tags, your game has zero characteristic tags. You use 6 tags to tell people it's an adult game. And the remaining tags tell it's a visual novel. So what do we know about the game by finding it in those tags?
Your description says this: Free-roaming and exploration and one of the screenshots shows the word quest. Are you sure, this is only the genre visual novel - or at all? Your passive discoverability might do better if you would use some interesting tags, instead of so many redundant tags. Why even tag renpy? You have that as meta information.
Anyway, what might be missing in this thread is this bit of information: major updates need "approval" to have your game featured in top of recent again. I guess we can assume that there is a filter that presorts the games maybe. But it is said that this approval is human approval. So someone has to hit an ok button to allow the time stamp update. And your game is only 3 months old. Updates are not major updates, they are updates.
Oh, and if you were to have some distinct tags, you would still appear in the top pages of those tags. Your game is only 3 months old.
This whole mechanic is dubious in my opinion. What about developers that update their game without a major update? There should be two "recent" sortings. Maybe three. And one of them should be by publishing date and be fixed. I was very surprised, when I learned that the recent sorting was neither a pure update sorting (which is easily abused without some cooldown to prevent spam), nor a publishing date sorting, but some unpredicteable mix of those two.
