Fun, hard and immersive.
It was a fun and novel experience. Felt like the start was kind of slow. One specific puzzle required players to be in the designers head, to solve the puzzle would likely have required a clue. We managered an educated brute force and got lucky. There was a puzzle that I could see having several limiting factors in it making it very difficult or impossible for some groups to solve and unfortunately I doubt any clue would help, Its possible our group just struggled way more then is normal though.
Atmosphere was amazing, it felt very immersive and was easy to feel like you were actually in a classic detective movie. the only criticism I have about atmosphere was the room was small and didn't have the greatest climate control. We had 3 larger players in the room and between our body heat and some of the props it got a little toasty, I also tend to be sensitive to temperature changes.
Our GM was amazing and made the experience way better, her ability to go from rules to story telling was truly a work of art and immediately brought our group into the experience!
Particularly interesting or different
Yes
3-4 players comfort wise.
Many puzzles would have been out of reach for children. One puzzle might be out of reach for some adult. Themes were designed for Adults
The gm did her part before entering the room and then at the end. Otherwise there was no live acting
Physically active

Those with mobility issues may have issues, but I feel like there is an easy enough work around the gm can help with if needed.
