I’m choosing not to visit a Notion site, but as help with what I can see: I second the suggestion if carefully choosing your website host. Immersive art projects depend on a setup you as the artist control, which is the opposite of what an AI-generated site offers.
Additionally, you might want to research how to write project descriptions. Your current itch.io projects aren’t conveying enough to me about what you meant to present. There are guides here on itch.io that break down what effective descriptions tend to look like.
