Nnnhgh...
Wasn't sure how to feel about this one at first. Initially it didn't seem very special- just some unlinked predictable pseudo-satanic imagery. But once I finished it I decided I liked it a lot better. The unusual placement of otherwise cliched objects- like the inverted pentagram wallpaper- combined with absolutely killer animation made this fun, and the ending wrapped it up well.
I think my favorite part was just after the bear goes down the well, when the room is moving around the boy.
