Very nice animations, art and sound design. It would have been nice if the difficulty ramped up though, I never really had to worry about the slow speed of dragging the sword since I was killing the enemies fast enough anyway.
The writing was also nice, it really added to the mood. One thing that was missing though was an explanation as to why this guy has a sword that gets more powerful when he drags it along the ground. That's pretty weird, it would have been nice to have some explanation of the reason behind that.
