sorry I thought I could just bundle the stuff into an itchio project link tot he index.html and it'd run in the browser, I think I've done that before... but but I left it a bit late. To be fair you aren't missing anything :)
fixed it so it opens, but I'm not smart enough to get the screen resolution right, and it doesn't seem to want to close .. I'd avoid it if I were you. I used to have bad dreams about apps I could never close.
