That was an amazingly fun playtest! I am just back from Palace Games, the folks who do the Houdini Escape Room in San Francisco. They're putting the finishing touches on a new room. After we playtested it, Chris the designer walked us through it. I'm glad he did. It had a three-act structure, which I didn't notice while in solving-frenzy, but which was pretty cool in hindsight. There was one team activity which was really cool because redacted redacted redacted oh gee whiz you should play this thing so we can talk about it without spoilering.
