Wow! I remember seeing this about a year ago and thinking "man, THIS is never going to see the light of day". It just seemed to ambitious to pull off properly, and I would have thought that the animation quality and length would be too hard to keep up with, but you managed to pull this off excellently!
The ending is everything that I assume you intended it to be: disturbing, depressing, and offbeat, though ultimately expected. All in all, great work, enjoyed the watch.
