The game starts with a landing page (as in the link). After pairing is done then the browser will automatically redirect to the game page. Did that happen for you?
That happened, but it doesn't actually seem to accept the info from the iphone. I see the accelerometer readings on the iphone, but it doesn't seem to do anything with the page. I tried reloading the page on my laptop and on my phone. Best I could do was get it to move all the way to the left once and then just hang there. Neat idea, hopefully you can fix it.
