Spur of the moment visit as our plans had to change. This room was all they had available to us at the time.
Enjoyable room with some nice theming (although I don’t know the Sweeny Todd story which helps but only slightly and didn’t withdraw from the experience). The puzzles were of a good difficulty, some easier than others.
I did think there was a bit of a red herring with a sequence of puzzles that lead us down a rabbit hole and me in to thinking that there was an issue with the locks! But after a few clues we were back on track.
I’d say a small group for this room is ideal, there isn’t the space or enough puzzles for lots of people to be working on at one time. It’s very linear in that respect.
Overall enjoyable.
