Cool concept! It was really interesting to move around the room, and sort of felt like I was in a room full of people.
Very challenging game! I only got to level 2. It felt a bit weird that you didn't know for sure whether you'd found a spy or not. On top of that, a lot of the interactions seemed to take a few seconds, which made it quite frustrating when I ran out of time, and realized I should have just guessed, rather than interviewing a bunch of people.
