As a seasoned escape room enthusiast, this was by far, the hardest room I have experienced. Puzzles were challenging and well-crafted, however, the ratio of time to the number of puzzles was inadequate. This room, to complete successfully for many players, would require at least 1hr15mins or more. I was highly impressed with the quality of these puzzles- but was unsatisfied with the hint system. We are unable to ask for hints ourselves, and game masters rely on the verbal/non-verbal cues to decide when they believe players require hints. Overall, it was a great experience and escape room, with a few minor issues on my part. I do recommend this room for highly-experienced players and groups of 4+!
