Our experience with the Pearl Experience was a bit of a disaster with incorrectly reset puzzles, broken tech and 2 GM's inside the game space with us who did very little to aid our experience. I'm giving the 1 1/2 stars purely because the set design is good.
The very first puzzle was nonsensical in that the team is to perform a game of cherades with their GM through a porthole in order to be given random letters. The GM has no way of communicating other than writing on a blackboard, and just kept writing "?" And angrily pointing at it as though that would make it make more sense
Following this we encountered 2 GMs in character within the space who didn't give us a moment to explore the space, instead pushing us from puzzle to puzzle and telling us what to do instead of letting us discover this for ourselves. Aparantly a lot of players like this as we mentioned it to our GM on the way out.
Several reset errors had been made within the game as there are 2 sets of puzzles that are designed for 2 groups to play simultaneously. We wasted a lot of time as our game had been set with a mix of pieces from both game sets.
One of the final puzzles also didn't work and our GMs in the end had to bypass the puzzle
As a final note, our GMs stood a few meters away whilst we solved what we could talking about us in spanish. We speak spanish, and they weren't exactly being polite about us
All in all, I wouldn't recommend the experience.
