I tried both Firefox and Chrome. But since I am Linux user maybe I will be only one with this problem.
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
I've added a linux build! Please tell me if it works, because i have no way of testing it
