I think the easiest build is to pump speed up to 8 and max out wave recharge, shield repair, and missiles. Then you just focus on dodging and let the missiles do the work.
If you're approaching slightly right of the center of it, press left. If you approach an asteroid slightly left of center, press right. Hope that helps. My max speed was 179 =)
Movement is crappy but it's a fun game. Sometimes it only lets me move in two directions. This game would be great if the movement was on par with mechanical commando.
