I've been fortunate that I haven't experienced any bugs, but man is this game hard. I've read plenty of posts talking about how easy the game unless you are on "Hard" or higher, but even with a well balanced party some of those fights are downright abusive. I'm guessing it could be a balance thing where some fights are too easy and some are too hard. For example, I managed to kill those two bears in the cave with without much trouble, but once I hit the temple I had some serious problems with the wisps and spiders. It wasn't completely insurmountable, but it almost seemed cheap.
I won't automatically jump to blaming game balance because it's possible that had my tanks been setup a little different some of the pain could have been avoided but maybe the dev should at least take a look.
On another topic, has anyone managed to be progress far without recruiting help from the Inn? I'm playing on Hard and I tried to avoid it and rely on the premade followers but I found the game was simply too hard early on to avoid it. Since you can't grind, I'm not sure to get a few more levels prior to the first major dungeon.
