A very endearing style of animation and great use of muffled communication to break language barriers. Inevitably biggest flaw is that the context is beyond present, hah! However the actual TV series is very damn good and the use of morbid simplification gives it such charm and only makes it more enjoyable to rewatch this each time.
I'll be keeping my eye out for the next one. Great job here! For those who "don't get it", you should treat yourself and come back after watching the TV series, and then all will click and work as intended on a less superficial level.
