Perfection.
Absolutely original, the voice acting was impeccable, the quality of it reflected the mood very well, and the paper animation style was a very fitting compliment to the dark, yet mysterious story. The animation itself flowed very smoothly, and my favorite part was indeed the music which didn't draw away from the animation. I would say this is comparable, if not better than the work of Katy Towell. Fantastic, loved every minute of it.
