A bit wierd.
It was vaguely amusing the way different body parts were 'killed' seperately.
And the music was a nice pick and there was some decent variation in methods of killing and the moves.
But it was all far too slow - it could have been speeded up for the most part and would have been a more enjoyable watch - and apart from that one novelty seemed too derivative.
Also, the graphics weren't that interesting.
But seriously, if you speeded it up, we could have gotten the same message, and watched all the same action in less time, and still understood it all just as well.
That'd be my #1 tip.
