A few notes: Prefer vectors over quoted lists '(1 2) vs [1 2]. There's rarely a case (outside of macros) that you want the former.
Instead of quoted lists of symbols: '(You cannot get that.) try strings "You cannot get that" Don't use defs inside defs. Instead move the defs to a global position and then use binding or set-var-root! to set them. Better yet, use atoms to hold their contents, even better yet, pass the game state into each function and have each function return a new game state. Instead of: (defn walk [direction] ... (def ^:dynamic *location* (first edge)) Use atoms like this: (def location (atom nil)) (defn walk [direction] ... (reset! location (first edge)) Once you replace symbol lists with strings, you can easily do this instead of syntax quoting: (str "There is a " (nth edge 2) " going " (nth edge 1) "from here") That's all I have for now.
