Out of curiosity, which browser and OS are you using? I’ve tested Safari on Mac, Firefox and Chrome on Linux, and Chrome on Windows.
Can you open the developer console in your browser (F12 in Firefox, Ctrl/Command + Shift + J on Chrome) and paste what errors it says there? Also have you tried disabling extensions or opening in a private browser window to be sure an extension isn’t breaking it? I ask as I can’t replicate what you’re experiencing. Chrome on my Macbook loads the game just fine, as does Chrome on my Windows test PC.
