The Emerald Phantom

This isn't quite as good as the very best games in London, but it's close. On Morty's ranking system, I felt it was right on the border between a thumbs up and a heart. The puzzles are satisfying, and I found the final sequence to be particularly charming and creative, and very well suited for the slightly fantastical behind-the-scenes-of-a-movie theme. The only drawback is that (as with their previous game Secret Studio) the designers have chosen to stock the set with old props-- which adds some authenticity, at the expense of giving the room a slightly musty and run-down feeling. We also encountered one puzzle that was broken, halting our game for a few minutes until the game master to come in and reset it. Not perfect, but a very worthy addition to the London escape room scene, and one I would recommend to any enthusiasts.
