Hi there, do you get the same issue using a different web browser? I have tested it with Firefox and Google Chrome and it works fine for me.

Strange why it works in Firefox. I tried running the game in Safari on my Mac but I couldn't reproduce the "UnityLoader is undefined" error, safari had some issues rendering the background but otherwise it worked. Are you using any extensions in your browser that could interfere with loading javascript?
