When I read your game description, what came to mind was the movie Late Night with the Devil.
But this is even better! In the human world, we have paranormal shows which humans obviously love to watch. It's interesting to see it the other way around.
It wasn't obvious what we need to do to entertain the audience. I imagine it to be similar to the game "Haunt the House: Terrortown"
Still, an interesting idea. Well done!
