I've heard a lot of people complain about the difficulty. They say they get wrecked by nekkers or trashed by other common enemies and guards even in the prologue; they reload a ♥♥♥♥load of times and some of them went from hard mode to normal mode, the weakest just switched to easy mode, which as well all know is unacceptable and for BIG BABIES.
I've been playing it on hard mode and it's gone smoothly so far, lots of fun. Don't mean to brag by saying this and the video just overdoes it, but really. Just be really cautious and don't be afraid to be mean towards the enemy. You have spells, traps, bombs, knives, parries and rolls, swords. Use them."
