In an effort to adhere to the traditional opensource software policy of "Release early, release often", we will provide links to a bi-weekly build of the game starting today. I must stress that these unofficial releases are the most recent stable developer builds and are far from complete, but they will show the progress of the game throughtout its development.
Again, this build is a very early alpha. So far the game includes: building walls, applying wallpaper textures, applying floor textures, adding a few objects to the scene, and a robot that walks intelligently around in the game. Try trapping the robot in a room.
Also, I have added a few more screenshots to the website.
