This is the Max Headroom shield type boss:
I can get to level 5 fairly easily, but no hope yet for the boss. What's a good strategy? I tried getting behind him and flying right into the cores to shoot em, but the amount of precise movement that is then required is too hard to make it a viable strategy I think.
However, when I stay in front of the shield he eventually starts coming straight at me, and I have no idea how to dodge him...
Has anyone defeated this boss?
