We were a group of 2 and finished in 55 minutes, but we did get about 5 hints.
This was really fun and challenging, but I wouldn't say that this is any more challenging than their other rooms like Gold Rush and Special Ops. Everyone says that this is the hardest, but I don't think the puzzles were that much more challenging the the ones in their other rooms. I think most people get stuck and lose a lot of time in the first part where the players are split up and need to communicate with one another across the two cells to advance, so having good communication and being familiar with the other people you are playing the room with really helps.
Overall, I thought it was fun to be split up from my partner. If there were more people, the first part would've been harder and more unorganized.
As with the other rooms from the company, the experience was immersive, and I thought the storyline was cohesive.
