So let me get this straight, I have to open the entire folder in a code editor (which I'm not sure how to do, but okay), then download a Python compiler and run it from the command prompt, and finally open the HTML file in the browser? I'm sorry, but that's just too many hoops to jump through for a game jam game.
I tried just opening the index file up, and it looks like this was made in Unity. I don't mean to be rude, I'm sure you had your reasons, but if this was made in Unity why not compile it as an HTML5 like normal?
