This is cool, curious to see if\where you'll take it post-jam.
Also, if you haven't figured it out by yourself, to make the web build embed on itch, you would need to set the "kind of project" to "HTML" and move the contents out of the "Web" directory in the archive so that index.html is in the root. Then you'd specify the archive as "this file is to be played in browser", and it'll display the game right on itch page.
