It is a barebones version of Asteroids: no score, no winning nor losing condition. Just the player shooting asteroids until none remains in the galaxy. Shouldn't be too hard to add those, along with more particle effects, stars, and other chrome.
It uses the keyboard 'class' that's on this thread, so it can be considered a field usage example of it.
