omg that was insane. But a whole lot of fun! (I did find a few of the levels, 6-6 in particular, 7-7 to some extent, I think maybe another one in the sixes, to be incredibly hard simply because it took a lot of experimentation to even score a single point. I can imagine putting in a "hint" button that would generate a random one-point-scoring configuration, just to have a starting point. Then again, I got through it without, so, you know, maybe not! :-) )
