Thanks for the comments.
von Lucky that link is a great start.
The maze part of this would be interesting as a fun family type game, of course jacked up in miniatures.
I was thinking each gamer gets a runner with basic weapons
and must survive a night in the maze ultimately getting out.
Of course there would be nasty Griever things to deal with.
The trick will be how to operate the maze. It should be changing as it does in the book/movie.
Randomizing the wall segments to move on die rolls might work.
Maybe using the numbered zones.
