I really liked this puzzle type. The break-in is wonderful, and the rest of the solution path is so much fun to deduce! A pleasant ride all the way through.

One of the most interesting and beautiful puzzles I've ever solved, everything involved in the break-in was so cool and intricate (and not easy to see), then the negative constraint was truly a blessing. Thank you for this lovely treat! ;)
