first of all, it's a json file? You also submitted this page to geojam? It's normally considered poor form to submit the same game to multiple jams.  At least unless it's said you could in the rules.  However, the itch page says you haven't uploaded a game to the page? Also, this was submitted 10 days ago at this point, before the jam started.  I'm not sure if this was a placeholder?

i dont know how to run your game?

this is a 9day old game?
