Hello,
I have started to work on your tool and toady, when I discovered that it was out also for Windows Phone 8 I just tried one of the templates (the infinite jump one) to test it on the phone and I found out that accelerometer does not work at all on a real device (Nokia Lumia 920).
Actually I have read that you are not able to test it but if you need any help on testing on a real device I am available for doing some testing.
By the way.
Really nice app :)
