I'm a bit surprised there aren't more comments on this, really enjoyed the atmosphere.
I like how the characters seem to have a bit of an "dysfunctional family" vibe, with father being well.....father. And mothra being the one who likes to make up excuses for father's "behavior" and then the "scared kid" and so on. And interesting to think about the main character being named dog, I wonder if dog being unable to get up is supposed to symbolically represent feeling tied down to a "family" they don't really like.
