Hmmm
First the bad. I didn't like the script, not even one bit. It was a combination of Devil May Cry I, with the last episode of Cowboy Bebop. Seriously, work it just a little so that it's not the action that we enjoy. Perhaps if, at the end, the king had been the knight all time along, much like Red Riding Hood (in the Flash Portal of Newgrounds).
Now the cute things.
Graphics, music and coordination were fantastic. The shadings were beautiful, the animations were smooth and not cheap. The effort was breathtaking.
