This is a neat lil' dungeon that you can drop in dang near anywhere which makes it versatile as heck. loved the dungeon key and random encounter table you included with your map. I wish the map had some loops, because I could foresee my players going clockwise through each room. It's not bad, but there isn't much opportunity for interesting path choices when exploring the space. That's a thing I always want to see and have in my dungeons.
However, the monster stats and also the boxed out player-faced information is incredibly useful and makes it easy to pick up and run without having thoroughly read it. I love those kinds of delineations, so thank you!
