I agree completely. Between the controls and the flying direction, it is hard to play. I use to play it on the Atari 400. Could maybe get to third level. I have it in Mame now, and have same issues. I find it hard to line up the targets and flight path to avoid obstacles. I remember firing constantly to figure out relative position of ship.
I wonder if this one is easier with a 4-way stick? I'll have to give that a try.
