Wow, looks like that is really coming along! Cool video. My one comment would be that as an observer it is hard to tell what direction you are moving when there are no referents onscreen. Most of the time there were, and obviously I know your ship points in the direction you are moving most (all?) of the time, but when nothing is onscreen I can't tell if you're moving, sitting, or gliding backwards with momentum. I think there would be a more visceral sense of movement, etc, if you had a parallax effect of stars / space dust going past, like a lot of 3D space games seem to do these days. Obviously I didn't do that with AI War, but I had considered it; I think it's more relevant in an action game.
Looks great!
