So despite the ending..
It was amazing. I loved how believable the art style/characters/soundscape were. It takes talent to make something work that well. And after seeing it and digesting it, the ending didn't really matter.. It was all in the suspense.
of course, it was mildly humorous that the mysterious badguy was infact a bunch of "furries", now that I've seen it. But while watching it and seeing the ending I was like "Awwww really? It could've been something badass.." But now, I realize you were probably going for that whole reaction, and for that I find it humorous.
I can definitely see your cartoon style be a sweet show on cartoon network.. not someday, but right now.
