So, I started out liking this map but I just couldn't finish it. I got stuck in the King's castle trying to find a way up to the 3rd floor but eventually gave up after exploring everywhere I could for like 10 minutes. I had a similar issue in the obsidian cave; it was just way too big and took too long to explore, and I couldn't even find the key to the maze. I really did like the story and all the story threads within each area. That was definitely the strongest point of the map. The pacing issues just slowed things down too much for me.
The side-quests were nice but the first one seemed very important and more than an optional quest. The second one was more side-questish but there was no way I was going to wait for 5 stacks of wheat to grow. I also had no idea where Rancher Joe's room was. Is Rancher Joe and Laurence the same person? I'm not sure how the player would make that connection before getting to the end of the lab.
It's a promising map, and very good if it's your first map. Thanks for making it! I hope you'll continue to make maps.
