First of all this game is awesome. The cinematics of just walking around are amazing. Plus the view that you get right from the start really makes this game one of a kind for our class. Just such a cool vibe.
Personally a more in line notification of when you do damage would be awesome. Currently its just a black box at the bottom but maybe a medieval writing type style on the bottom would've looked cooler. Also although the health bar is pretty cool, it is quite basic so maybe adding more feature to that would've been awesome.
Great game though :)
