I think Hellblade shouldn’t be played on harder difficulties, because they are not harder. They just make you take longer to kill the enemies.
I started that game with the adjusting difficulty which was good because I needed some time to learn the combat. But as I got better and better the “difficulty” also increased. So by the end of the game the enemies were super spongy and just a slog to go through. Annoyed I lowered the difficulty and the game got really awesome for the climax. It felt really appropriate, especially with the direction of the story.
