I would have been stuck on this if I didn't do a few pipeline levels. This feels like a good introduction to future levels where you have to organize blocks.
There are a truly staggering number of 79s... the 77 feels great to find! Finally finished the original 13 stinker levels; I hope someday there will be more.
That one was for me of the type where I just try routes, then eventually one works, and I don't know why this one and not another. I remove one star because I have less interest for those. It doesn't feel like really "solving" it.
I enjoyed solving this one. I was lucky as I understood the concept just by watching the board before to start, so after that, I just needed to optimize a bit. :)
