I found Dread Mountain to be an overall extremely grindy and non-challenging experience. I won't pretend to have tried a lot of YourMaster's maps, in fact I've only played Death Clock, but it was certainly a more enjoyable experience than Dread Mountain. I did Death Clock in one sitting I believe, while Dread Mountain on the other hand I had to do in three separate instances due to boredom.
The start up is probably the most interesting, actually, as there isn't much to work with and there's some strategy to the first fight with the Bile Demon against the two Dwarves, as, at least for me, he was going to be killed unless I retreated to heal before re-engaging. There's also the initial spark of interest in the custom built structure that spawns Imps.
After that... the map actually starts to take a drop and never really recovers from that. The pacing just starts to slow down, I think more so as the map goes on. Due to the lack of Sight of Evil, there isn't a whole lot of exploring that can be done (unless I'm expected to save state abuse or explore the map beforehand, neither of which are very legit). I have just a few small Bile Demons, so exploring blindly doesn't seem to be a very smart move.
The next thing I'm directed to do is invade a Hatchery full of Barbarians. However, they're way too strong for the amount of Bile Demons I have at this point, so I have to train them. This wouldn't be so much of an issue if it weren't for the fact that I also have to do a lot of research, most notably to obtain the Prison and Torture Chamber as converting is a big part of the map to expand the player's army. Soooo... I have to wait for my Bile Demons to get up to some decent level while also researching said rooms so that I can convert the Barbarians and any other enemies I encounter. And there actually isn't much for me to do while I wait, outside of Imp management by speeding up the mining process of gold, which gets repetitive really fast.
And that trend pretty much continues for the rest of the map. Due to the lack of information, it seems to be a smarter decision to expand like a turtle, by grinding out my creatures in the Training Room and then grinding out any enemies on the map... slowly. Meanwhile I had to do a lot of Imp management so that my creatures could keep training and I had to mine relatively fast to keep up with active costs, and that was just extremely repetitive and unfun.
Yes, I can get more Imps, but there's no indication ingame as to how or if that's even possible. Really, it's only ever mentioned in one of the bullet points in the description of the map. It's right in the middle, where it can be missed and/or forgotten, especially if the map is looked at and downloaded in two separate instances like with me. I never failed to convert an enemy and I always executed unwanted Heroes by slapping them as Ghosts really suck and take up living space, so I never found out about it by accident either. It really should be mentioned ingame regardless, as that would have somewhat helped with the grindy experience of the map. By that, I mean it would have removed the one task I had to do while waiting for my creatures to level so I'd be doing nothing instead of doing a repetitive task over and over again with my measly four Imps.
Another thing that's kind of annoying is that the majority of the army becomes pretty much Bile Demons and Heroes (and an Orc I guess), so I end up not really needing any other creatures. Yet, the Portal keeps making them and I don't want them due to living expenses, as I don't have a gem for a good while. I kept tossing them away for a while until I got tired of doing that and just let them do whatever.
I will say that, as an example map for the new terrain type, it's decent. I didn't realize what I was supposed to do until I noticed that it was absolutely impossible to engage with Blue, so I began to look for alternatives and stumbled upon the caves. I'm not sure if they're tricky to notice, or if I wasn't paying attention due to being somewhat zoned out and bored by that point. I was pretty much just mining out random areas to find the last Heroes as I had a strong enough army by that point to fight Blue.
There's not that much more to mention as that kinda sums up the map as a whole. A slow and grindy experience. That's also not all that challenging either. At least, from what I played, because I have yet to finish it and atm have no plans to finish it. I'm not fighting Blue. I know what I have to do, but I'm not going to spend the time to grind him out with as questionable a mechanic as the Barracks while trying to fight Lv10 Dark Mistresses (and archers I guess) who are much more OP than I remember. Nope. I'm out.
While I don't really like the map that much, I still would rate it better than most user made maps. Although, that's more so to say that most user made maps aren't that good. Dread Mountain looks pretty, I guess, but it certainly does not play well and led to an overall unenjoyable experience for me.

Final Score: 10/10
This map is absolutely perfect and deserves the most perfect score of 100% success. Do not change a thing because that would imply that there was an imperfection and that something should have been changed, which would indicate that this map is anything less than a perfect score of 10/10, 100%. Would not finish again.
PS: I noticed that the Demon Spawn would randomly get annoyed, yet for a while I had absolutely no idea why as there's absolutely no indication as to what's bothering him. Eventually I figured out that he was getting upset due to not training. Was the Demon Spawn always like that or was that something that changed in FX? Either way, it's very silly due to the lack of player feedback.
While I did piece everything together as it happened when I locked the Training Room door, I was only able to do it because I remembered talk about the Demon Spawn getting annoyed due to lack of training (as a possible change I think)
