What I didn't like
I’d love to have a guide to the framework, and how interactive it could be, how much I can go in one direction or another, how much I can interact with the actors without breaking the play, etc.
The top secret message (the Society knows what it is) could have been better—shorter, better ediiting, and especially better audio.
My overall impression
Loved it! This is just what I want to experience with immersive theater. It was engaging, entertaining, full of excellent performances, intrigue, and most importantly, narrative agency (choice) for the participants.
I am definitely going to incorporate some of their gimmicks/tricks into my own larp (live action role play) and immersive experiences.
