hey, thanks for submitting a game! I see it is an html file but it is not playable in browser which is a requirement for a jam. this also makes it much easier for players to access your game.
this is easy for you to fix. in your game's settings on itch, for "Kind of project" select HTML. Then you can upload your html, or a zip file of it and click the check box "This file will be played in browser". I also recommend clicking the checkbox "Automatically load on page start". There are a few other settings there you can configure for how your game is displayed.
