Pretty fun! I particularly enjoyed shoving entire rows of boxes out of the way.
One suggestion: Connecting wires was slightly more complicated than I expected from experience with e.g. Zelda puzzles, where you just drop conductive material down. I would suggest changing the color of the boxes that are part of a conductor to match the color of the wire, because the colorful endpoints gave me the expectation that other boxes were also conductive, so I tried extending a wire to reach across a gap by adding boxes at first, rather than anchoring the wire and then stretching it to the next point.
Thanks for sharing!
