Really cool, I'm always extra impressed with 3D games and the bosses had a 'biblically accurate angel' vibe I liked!
Giving up abilities was a cool twist and in terms of presentation reminded me of the early part of KH1 where you 'give up' a path to decide your stats.
One user friendly thing that was a little rough was the camera tilt on hitting A or D messed with me a little so I wound up just using the mouse to turn lol
all in all, really impressive!
