What we have here is an AiJet, in red, tracking my player jet, in blue.

So all I need to do is make up some interesting AI patterns, have some kind of enemy emitter / dispatcher to get those enemies on-screen, and then maybe add a couple of superweapons and a boss or two.

I can probably do that tomorrow.
