Incredibly smooth.
I'm in awe of this. The punctuation of the movements and the swiftness and fluidity of the maneuvers and kills. The blood effects were decent as well as the sword clashes. Speaking of which, the swordfight was my favorite part, by far, since it had so much movement and skill involved in making it.
Only reason you got a nine was the overuse of SFX, the test-animation feel of this, and the lack of original sprites. However, you should feel proud of what you did. Congrats.
