Rewatched this and its good all around. I don't know why I said soemthign about it being "simple". I apologize and was quite silly, if not stupid and pompous or assuming. I thought I was being constructive.

Nice work. I love your ability to convey what was going on through mere sounds and what was on the screen. Perhaps its simple to do, but whatever, I enjoyed it, even if it took somewhat of a rather dark turn that I wasn't expecting.
Anyway, hope you get good grades for your animation!
