Good set. Logical puzzles. Two issues - 1 the clue-giving was not functional. We got clued several times when we hadn’t asked for one and always for a puzzle we’d already solved. 2 - there are many four digit locks with no indication of which goes with which puzzle, so you have to try every code you get in multiple locks until you find where it fits. We wound up using a “real” clue because we hadn’t tried one of the codes we figured out on all locks. And the GM had to come into the room to deliver that clue. So both issues collided. I’d still recommend playing this room. It was good. But with a little rework could be much better.
