Really good game. Puzzles were medium to hard, very few easy puzzles. We had a group of 4 and did escape, but with a fair amount of nudges from our fun game host. This room was a lot of fun for our group, I would say 4-6 is a good number, but 6+ would feel cramped in this small space. Linear at times, but I think our team went "out of order" and it didn't matter - and a good mix of tech, puzzles, and locks. Really enjoyable, especially with the GM. It was scary at times but well done, with 1 jump scare if you're the lucky one. Hint system was awesome. Some of the puzzles were, what our group considers, absolutely very almost impossible to figure out without a hint. Loved the ending and we laughed a lot.
