The app asks me if I want to launch "nw" or "index.html".

If I launch index.html, I get the same thing I would if I just opened that file directly, with the same problem, only there's music now.

If I launch nw, it takes me straight into the game. I assume this is what I'd get if I clicked "play" and it worked.

Yeah, nw is the way to play. Does this work for you or do you want to play through the html page instead?
