The cover art is genuinely good, and it is doing less for you than it should because of the line sitting next to it. I sell asset packs on itch, so weigh that.
The one line itch prints under your cover on every browse page is a Steam URL. With the short description field empty, itch falls back to the first line of the page body — your profile grid confirms it: the Worlda: Demo tile’s text is “Wishlist now on steam! https://store.steampowered.com/app/4700370/Worlda/”. That is the entire pitch a stranger gets. “Infinite 2D top-down world: build, craft, mine, fish” would do far more work in the same slot.
Your cover and your first screenshot promise two different games. I rendered the 315x250 tile and looked at it — the bear and the title both survive the crop, it reads well — but it is a painted storybook illustration, and the screenshot immediately behind it is the crafting and inventory grid. A pixel-art world shot in slot one would keep the promise the cover makes.
