I liked the map. It's really good. I thoroughly enjoyed it. Everything was fine: lots of monsters, but there wasn't any real tension.
I suddenly remembered my first maps, and they were really bad compared to this one. Yes, it's pretty simple, but I don't feel like giving the author any recommendations. For a first map, it's really good, and I believe the author will quickly gain experience and create masterpieces.
Thanks for the fun. And good luck!
