I finally got him down. I took one person's suggestion to make a one-button rotation. Had to learn how to macro a bit to do it, but it was far easier, and I was much more able to concentrate on the maze. Once I had more focus on the maze, and since I knew most of the patterns from all the other attempts, I finally got it down.
Next one I'm stuck on is Nibbleh, although apparently I'm just gonna have to be lucky and hope he doesn't stop for a stupid reason, as he seems to for everybody else. He's definitely done it to me a few times. Ah well, maybe I'll get that one lucky fight.
