Very nicely done.
Clean and smooth animation, bright colors, exceptional sound. If only every animator cared as much about their submissions!
Just one gripe, though. While I get the gist of the cartoon (I think), I don't understand the Kanji (or the zombies with stickers on them). It may detract from the cartoon, but what about a version with English subtitles to translate any Kanji used? I'd like to know the full meaning of the cartoon.
