I’ve mentioned Fantasia and The Black Cauldron above because there’s something about the combination of dark fantasy and slapstick animation in Tsioque that brought them both to mind. Admittedly, I haven’t seen The Black Cauldron for years and looking at a few screengrabs has convinced me that it might not be quite the film I thought it was, but I’m sticking to my guns here. There’s something of Bluth in Tsioque as well.
Whatever the merits of my references, Tsioque [official site] looks like a delicious slice of fantasy, starring a young girl in a dark castle. You can play a demo right now or read on for more information.
