I was not very good at this, so the instant retry after dying was appreciated. The first battle in particular was the hardest (due to the small size) and it took me a bit to figure out I had to keep pressing 'Enter' to attack, instead of repeatedly pressing it. In the end my strategy as Oldhar was to stand still and keep attacking hoping to outlast the enemy.
I enjoyed the story and the unique Oldhar it had (same with the other darksiders).
