Moving quickly seems to be a recurring element of your maps! I suppose I'm a bit out of my depth, being used to slow plays / building up perfect dungeons and armies in the original game. I haven't played a great deal of custom levels/campaigns. What I find troubling is progressing too quickly and making a mistake that costs the game. For instance, you've laid out basic walkthroughs, but without them, figuring out the correct order in which to progress through the map can become a case of trial and error. Knocking down the wrong door, triggering an event you weren't ready for, opening a pathway you should've left unexplored for the time being - all of these mistakes can easily be stumbled into on an initial playthrough.
Come to think of it, my main problem is with resource management. Give me a map with a scarcity of gold and it's gonna take me a while to work through it.
Edit: I beat it
