Same gameplay as LD18 submission, just changed a couple classes to allow the game to  be controlled via a game pad and added a splash screen for selection of the active controller.  The last remaining change was to tweak the rendering to allow the 800 by 480 resolution to be displayed centrally on a TV screen.

The windows compo version is still here  and appreciate all the feedback: http://www.ludumdare.com/compo/ludum-dare-18/?action=preview&uid=1516
