Having completed Brian's Brain and Brian's Variation before this, this level was somewhat a breeze. But without those it would've been very difficult to see the right trick. Really cool level, though, and a nice optimal path found.
Finally managed to take this one down. Not sure why it took me so long, especially after playing Brian's Brain, but I'm glad to have gotten it. Very nice idea.
For some reason, took me a while to see. But not that hard once you see it. Still feels way too busy, though, like most of the difficulty is just distraction.
Editing to respond to Mage's comment: I recognize that that's the decision you made when making the level, I just don't necessarily find that a particularly compelling part of most levels. I don't say this to say you shouldn't make levels this way; ultimately it's your decision what kind of levels you make. But I will still give my opinion in reviews, which is all this is.
Very nice puzzle, I like the process of figuring out the solution. Was a little surprised - I went straight from 100 down to 96, so I'm not sure where the potential for a 98 was.
