Incredible level. I love that using naive displacement pipelining techniques isnβt enough - those just beginning to understand them (like myself, at a time) may be confused when they seem to not lose any moves, yet end up 2-off. This level is a beautiful demonstration of additional techniques needed when ***************************************************************** Absolutely fantastic, so glad to have done this one.
Revising this rating to 5 stars. Suddenly had a thought today about design, and gave it some deep thought, and while I personally did not find the design or challenge that substantial, I now do not deny that the design aspect is valuable, and so I have updated accordingly.
