I have not played it yet, so this is not the technical or story feedback you asked for — it is one page problem I can prove, and it is cheap to fix. I sell asset packs on itch, so weigh that.
Your short description is empty. The page’s meta description falls back to “Available for Windows, Linux”, which is what itch prints when there is no tagline behind it.
You can check it yourself in one click: search your own game. Your result cell goes straight from title to author to Role Playing to the platform icons, with no description line at all. On that same results page, 41 of the 53 cells have one — the games directly around you are using that line to say what they are, and yours is blank.
After a year on a custom MonoGame engine, “2D JRPG with turn-based combat” is one line of text and it is the only pitch most people will ever see. The cover itself is fine, incidentally — I rendered it at the 315x250 tile size and the pencil-on-lined-paper look survives the crop and is genuinely distinctive.
