It's been sitting there saying "Loading..." for the last few minutes. My guess is that the web site probably needs Javascript turned on in order to work correctly. That's not a problem, as I can see that the functionality of a game requires the abilities of Javascript. However, you should put up a message along the lines of "This game needs Javascript to work - if you want to play, please turn Javascript on. I promise to not do nasty things". And you should serve from HTTPS.
