    It seemed like an additional theme was a complete lack of unclued regions (which also means no “1” or “2” regions) until the very end of the puzzle, where you needed them to solve a last little riddle. It enjoyed seeing all those snug little fits locking together.

    Very tough puzzle.I had to obtain a lot of contradictions before i could proceed further which could have achieved by grandmasters with a bit of visualisation.I liked the way the last tiny bit filled .

    Well, I won’t repeat about the last step; that’s mentioned already. The solve was pretty smooth; most of the time it’s “this can expand here” (where “expand” generally means only one new cell), although I needed a few small bifurcations. The chain reaction is marvelous.

    I’s compare the setup of the first half of this puzzle to setting up the pieces of a Rude Goldberg machine, and the second half to setting the device in motion. Very nice design/flow.
