This scene just keeps getting better!

F to start. Hold Enter to slowly cut his hand off. If you fail to cut off his hand in time, the pendulum will kill him.

Update: I've fixed the glitch where when your using the laser, sometimes it reflects off his arm and cuts his head off. The problem was quite simple! The object protecting his head was not immortal, so the laser would cut right through it!...

Update 2: I guess that glitch wasn't 100% fixed yet. But it is now!

Here's a movie I made of this: http://www.youtube.com/watch?v=rdlVLaIhz8A
