Thank you for your feedback. As for damage - did you not notice the red vignette that appears when you got hit?
I did notice that I did get a red vignette when I did get hit, but it was kinda hard to tell when I was about to get hit by an enemy and when I did get hit, it was difficult to tell why I got hit. Perhaps just telegraphing attacks more clearly or adding a more noticeable reaction to damage might have helped.
