Finish him!!
Lol, Ok so I was going to score you about a 5-6, for lack of options (ie no block), but the end of hard mode totally made up for it! Pretty good "real life" definetly one of the better ones i've seen on here and much better the FPS in real life.
To those having trouble here are a few hints:
When he completely turns his body after the shuffle hit right key.
If he doesn't show either fist hit the up key.
If he shows his right hand (your left) hit the left key.
There is plenty of time to react (~2 seconds i think) so just don't panic. Keep you're cool and its pretty easy.
