Well, something is clearly very broken. Have you tried a different browser? If that doesn't work, I'm planning to make a build for Windows once jam is over
You know what, since you've waited for an hour and tried different browsers, I think I can at least try to make a Linux build for you.
And if that doesn't work, my game will be on GitHub, so you can build it yourself for any platform you want. It's on GitHub already, but not the latest version
