It's a House RPG! I had a fun time reading this. And I plan to try playing it with a friend or two. :)
The only thing I feel it could flesh out more is a solid way to end the game.
Based on the inspirations and the tables, I would use what the spirit desires to build up a mystery for the players to solve. Find the house's desire, fulfill it and survive in one way or another.
But the game does make it clear escape is unlikely. And if House (1977) is the inspiration, then a game of Nerve should focus on the horror vibes and scenes more than the actual escape.
