Have you tried opening your browser console to see if there’s any error message there? It can often point you in the right direction.
I did, this is what I found:
Uncaught SyntaxError: Invalid or unexpected token
v6p9d9t4.ssl.hwcdn.n…ealpong.loader.js:1
Uncaught ReferenceError: unityFramework is not defined
at HTMLScriptElement.r.onload (v6p9d9t4.ssl.hwcdn.net/html/3538892/Build/realpong.loader.js:1)
