Gorgeous puzzle! After I finally found a way to break in to the puzzle, and I found it extremely well hidden and quite a surprise, the puzzle still resisted until halfway through, then it collapsed. Very rewarding solve, thanks

I thought it would be smooth as I filled in initial pencil marks, but it ended up as a very tough break in for me, but once I deciphered the ten lines it was smooth. Very enjoyable challenge, thanks.
