Nice work! Why won't You update it into repositories, as alternative "edition"?

Also, wouldn't it be possible to mix bets of both worlds - include both options, selectable via single configuration file (normal text file, parsed on game start, where selected mode would be defined)?

This way, you could just add Your version on top of existing one, to extras-devel. It would allow to play both via accelerometer and touchscreen (on the move), and via mouse and keyboard, when appropriate
