Hit direction indicator
I would like to bring up a small suggestion. It can get quite confusing when fighting a group of enemies in melee range. NPCs tend to surround you. It would be great to somehow indicate from where you recently got damage. Maybe some arrows circular around the center of the screen like in most FPS games would be nice.
Example I found on a quick google search:
I agree, this would help a lot with the UI/combat, but maybe have it on the edge of the screen instead of near the center.
Could even do like a blood spatter on the side of the screen.
