I've played about 3 hours and after dying in a boss fight, I can't progress, the way is blocked that wasn't even locked before. Other bugs is that i can't change difficulty, and when saving the game and coming back, I'm not at the same location. I'll stop playing for a while in hopes that this gets fixed. It wouldn't be so bad to start over except that the map feature is useless and it's very hard to figure out where to go next.
