Millions of copies already sold!

I'm no where near done with this game, however I do have a "playable" version that you guys can download and try out for freeeee.  

You move with wsad, and you aim and fire with the mouse.  Try to protect "earth" from the asteroids until your population is high enough. Don't let to many asteroids hit the earth or you lose!
