not sure why the rating is so low on this puzzle, should be 90s at least imo. Really enjoyed, thanks for setting :)

iEtsh: I appreciate your kind words, which are a great motivation!

Unfortunately, the vast majority of solvers simply close the page once they finish the puzzle without submitting the solution or leaving a rating.
