I’ve been working on this game for some time now. Its a twin stick shooter in which players settle a land and then defend it from attacks whilst attack lands owned by their Facebook friends. The graphics engine uses BitmapData blitting to render large numbers of assets quickly. The system generates landscapes using perlin noise which can be seen in this render of possible lands – http://www.flickr.com/photos/tomdanvers/5765825135/lightbox/. I’m allowing players to see my work in progress builds so I can get feedback as the game progresses.
