Wow, I can really see this being done.
I do have a bit of a nitpicker problem with the vectors. Beside that, the animation is really well done, and the script looks good. I do have another problem with the part where the guy jumps to the other part of the cliff. He makes a strange yell that almost sounds like it was yawned out.
I really hope this project kicks off soon, and I wish your project success. It's definitely headed in the right direction.
