HTML5 Mobile Game: Alien Invasion
A basic mobile shooting game demo built from the ground up in the first few chapters of my upcoming book on Mobile HTML5 Game Development.
The code, clocking in around ~500 SLOC with no external libraries or dependencies is up on GitHub
The game is Canvas, so performance is only good on iOS 5.0 Devices currently (iPhone, iPad, iPod) but it should at least run on any Webkit browser, hopefully Android will get hardware accelerated Canvas soon*.

*And of course, less then one week after posting this, Google released Chrome for Android w/ GPU Accelerated Canvas. Ask and you shall receive.
