Well, for some definition of 'advanced' you can look at the Asteroids example. It has multiple lists of entities in the big game state hash, and has functions which pull them out and operate on them. The full hash is only used in a single, small function. But honestly, I think the Asteroids example may still be the most complex real-time game written in Clojure so far. I think the approach described above should scale pretty well, but that's an unproven theory. Hopefully this site will encourage people to find out.
