This doesn't work on iOS and requires JQuery
I use this code on Blackberry Playbook and Nexus 7
The Nexus 7 needs the right and left control values reversed
The following is a big hack that overrides the built-in control system but makes for very intuitive play.
On the tested devices you can tilt the tablet left / right to move in that direction, touch anywhere on the screen to fire and flip the device away from you a little to jump.
It's extensible - you could easily use the Z-Axis as well or reverse the jump code for a 'down' command for example
A modification I'll be making shortly will allow different parts of the screen to do different things based on where the touch event takes place
The touchmove binding prevents scrolling of a webview if anyone's wondering
