Being Escape Stirling's room built by the roster of talented GM's there, it was always going to be on my 'must-play' list. First off, you can tell a lot of care and craft went I to this game. They really strived to create unique interactions and it paid off. Every puzzle was a joy to solve.
The immersion was also top notch, from the elevator that takes you down to the depths, to the silly Easter eggs, and lest I forget the occasional chance to roleplay and make a fool of myself, it was all excellent.
In terms of difficulty there were a few times another member of the team had to come to the rescue with a different perspective on how to solve a puzzle, but that's part of the joy of a well constructed room. Nothing felt unfair or beyond comprehension. There were no leaps of logic or "guesswork", everything made sense. Overall it was an excellent room from every angle
