Lakai: that was a bug in 1.4.2b, now it's fixed
Teldrassil:
1. At this moment I am using standart unit "acquisition range" to make them attack selected tiles, which are hostile. Unfortunatelly, the built-in pathfinding system fails for some reason. I am working on a system for workers, which would assing the work better (including embrace lairs)
2. I already tried to balance the creep power multiple times, it's very hard due to the fact that heroes cannot heal. And even if the creeps don't hurt them, they can be used to hold them long enough.
3. You mean main boss or minibosses? I haven't seen boss die from degeneration ever (though someone else already mentioned that). I will try replacing this by life regeneration aura.
4. you mean too weak?
5. more content is coming, now I am still focusing on gameplay. I am planning a whole set of bosses
6. you choose that by building either secondary or primary dwelling. If you could spawn any units at any dwelling, the dungeon lords characters will need to be removed
7. you mean when the same minigame starts for the second time? that's the only way I saw them fail, and I hope there aren't any more.
takethat:
Many of the game mechanics lead the Dungeon lords to create bigger (=larger area) dungeons. If they could build a building every second tile, or move minions limitless over the entire dungeon, they would create giant room with an army of skeletons, which would either crush heroes, or it will be defeated and heroes walk through the rest of the dungeon undisturbed. Therefor the units have timers, so they can't move so far away from their lair, there are more entrances, so the dungeon lords can't know exactly where the heroes come in and rooms need to be further away from each other.
Also, the creeps are pretty weak, because heroes can't heal. And regardless of their strength, if you manage to outmaneuver heroes, they won't get to the dwellings and minions will spawn faster than thay will die.
Traps are supposed to work on dungeon inhabitants. Building dungeon shouldn't be about spamming lots of traps, dwellings, minibosses and everything else in one room, where the heroes get crushed. Also it provides further tactical possibilities for heroes, which can use your trap agains you.
The game already takes ~30-40 minutes, which is exactly what I wanted, making it longer could be boring.
Thanks everyone for suggestions, I will try to present new version as soon as possible
