I played some of your maps during the week and can gladly give some feedback.
The most important thing first: I had fun with your maps
At first I played Dangerous and Secret. I know it is meant to be played in multiplayer with another human player, but I tried it with an AI for blue anyway. Also I downloaded the first version you posted and did not use the one from your following post.
The difficulty was nice overall and I had a fun "slowly advance into enemy territory"-game. Since the AI keepers are quite bad (played V1.7) my blue "ally" wasn't much help and had no impact on the game. After a long game I finally cleared all hero armies and hero lairs but found no way to get to the green keeper. If you could clarify how it is supposed to be played or what I missed that would help meSince the map seems to be very big I had some crashes from time to time and at some points could not build any more rooms. I fear that is just the DK2-engine on big maps.
I also played Level10 and was in for quite a surpriseWhile the other keepers very sadly too weak to pose any challenge the first half of the game was really really really challenging. I had to start this map several times because the hero armies would simply overwhelm me. After several weaker waves the heroes would start to invade with lvl5-9 units (for example 3 lvl9 bile demons, lvl5 skeletons or higher lvl knights) which spelled my doom many times. The heroes would also tunnel into my dungeon every time so hiding was not an option. When I finally managed to survive long enough to convert enough strong heroes to my cause I had practically won the game. Since I started the map several times I noticed an odd bug/feature: Every time I started the map from the skirmish-screen the spells I started with AND the spells I could research varied widly. Sometimes I had 2 spells from the start and could research 6 total. One time I started with no spells (no summon imp is harsh). Another time I started with 2 spells and could research 10 total. During the game I finally won I started with summon imp and heal - one of the reasons this time I managed to win.
Overall thought: While something seems to have gone wrong - I doubt you intended those lvl9 units to attack so early - I enjoyed the map surprisingly well. From time to time I like the kind of challenge that makes you restart a map several times and work out a suitable strategy.
I also started Twin Brothers, but since I played without the allied keepers the enemy waves became too much very quickly. Will probably come back to this one when I need another challenge.
Just bear in mind, that probably many ppl - like me - only play DK from time to time. It is possible, that some ppl will only enjoy your maps about 3 years from now![]()
