This is a very compelling premise akin to an episode of Black Mirror or the opening of Prey, which is a great starting point for a one shot! I like the visual treatment and I think especially in print this will really pop!
I do feel that it could be tighter in the execution, as in reading I found a variety of edge cases that could cause friction for Warden usability. It's not clear from the maps specifically how the studio and set fit together, and the "rules" of the game show feel a little vague. I feel some more fleshing out on the "it takes the form of your worst fear" front would be welcomed by a lot of Wardens who struggle to come up with that kind of stuff ahead of time/on the fly, and also good to address potential trigger warnings with the players. People might be prone to taking that concept too far if they're left in the wind to improvise.
In the end I think that with some cleaning up on these fronts, I think you'll have a really slick module! You can layer in like three twists in as many hours and keep a canny group of players on their toes. Letting them end it all with an interview gone wrong (resisting sedation) is the exact kind of memorable end-scene I love to see in a one-shot. Good work!
