I've been playing this for a bit and I'm currently on the third campaign mission. This game is extremely poor, practically everything is badly designed. It's like they released it a year early without testing any of the mechanics, or actually playing it at all. A lot of the mechanics don't even work. The concept itself is pretty good, but these developers didn't even come close to bringing the idea to its full potential.
Ok, so I get the concept of being the lord of a dungeon. The evil thing at the bottom of the cavern that's trying to kill the hero. But this is just.. terrible. Bad. Terribad. First of all prestige items (decorations that are supposed to lure enemies about) don't seem to work very well at all. Sometimes a hero will even turn around and go right back out the way he walked in, regardless of what you've placed and where. This happens with gold, too. And the "take half the gold and move on" mechanic makes absolutely no sense to me whatsoever. Secondly, Enemies will 'aggro' the hero through walls, making the designing process of the dungeon a nightmare. And while the timer on the hero gates is continually ticking down, you're given little annoying side quests that you need to complete at the same time, almost guaranteeing that heroes will escape or even reach the dungeon heart.
Oh, and the combat itself? Laughable. Most of the time after engaging a hero head on you'll not even face the right way. You'd be better off rolling two dice and slamming your face into a wall.
I mean I can just keep listing thing after thing, but it's no use. The list will never end. While I understand completely that it's still very early, most of these issues are just embarrassing. No manner of patch can fix this gameplay.
