Love the concept.
Voice acting ruined it. Saw's voice wasnt a voice, but more of a loud white noise. Noises like that mess with my brain. I almost broke down because the low, deep, whisper, was tormenting my SOUL.
The wall climb was annoying. How many times did he fall... 6? 7? I dont remember. It was rather obnoxious.
When Santa was "screaming," it sounded like he was punched in the stomach so he couldnt breathe. He had his legs and arm torn off(unrealistically, at that)!
Ahh... what Im saying is that it needs work. Alot of work. Dont bother with me, Im just some Internet nobody who is like many others. I loved the concept though, just needs a bit of spit n polish.
Seeing as this is your first, GREAT effort. Up there was the critic in me, so dont take it the wrong way. Also, many congratulations on getting your first submission frontpaged! That really is awesome.
Flame me if I sounded harsh, but please know that my intentions are pure. Merry Christmas(though its a few hours past), and have a good one, mate. :D
