Holy FUCK.
That was WONDERFULLY disturbing. I love the animation style. It's fantastic. The voices are superb as well. I really hope you continue with this series, because it's so good.
The only thing I didn't like was the bear guy at the end. I know he was supposed to be kind of a character foil, but he really didn't fit in to the setting. He was far too serious and intelligent. If he was a bit more like the other two guys, kind of childish and disturbing, he'd fit better.
