"Yes, I remember that room with the double doors. I killed a bunch of giant rats in there. Good times."
One of the aspects of pre-battlemat/pre-vtt play I miss is describing dungeons to players and then seeing what they draw compared to the original.
The verbal description maps could become interesting but unless you had a player with a mapping fetish they weren't too popular in my past gaming circles.
That looks really similar to the map for Zork II - did you ever play that? Maybe that game helped inspire this map?
