Love that a game is trying to comment on drug use and its affects on relationships. Hope it all comes together. If I remember correctly, the developer talked about how it's about his (or his fathers?) experience with drugs and what it did to their relationship.
Made me think of that too. Seems to be from a child's perspective, that you can find a "cure" for this person's addiction while they're not being the monster, and things will turn out ok...nice if it were that simple.
