Decent
But not excellent. It was a little difficult to tell what was happening (and I understand that in the Saw movies, the camera jumps around a lot, but still, it could have been a little clearer in this.)
Also, I was a little put off by your deviance from Jigsaw's script. The format is:
"Hello, (name). I want to play a game. (Explanation of why I am doing this to you.) (Explanation of what is going to happen to you, and how you can escape.) Live or die, the choice is yours."
We don't know WHY Jigsaw is doing this to the Clock. However, since a Clock is being tortured and (we can only hope) killed, it makes it a better flash automatically.
