That's amazing, I don't have the time to watch it till the end now, but.. WOW!

Only two things for now:

I think the skeleton are losing too much bones..
Maybe let the lose ~4 to 8 bones on a hit and make the bone sprites darker so that they fit to the skeletons.

Maybe you could make the rotation smoother when pressing another direction key.
It can be only visually like I did in Dragonrise or like it is done in NWN.
The character moves to the desired direction an while he's doing that he rotates towards that direction (fast but not immediate, absolute movement neccessary, not relative)
