I've enjoyed all your games so far (as far as I can recall), and this is no exception. Smart pun/concept/idea (I think I did a double take when I got it), and strikes a balance between "sweet" and "surreal". Very light and simple, but I think it'll stay with me for a long time.
@Chaoseed: Think of it as a pun. In the world of this game, a "moth-er" isn't a female parent; it's the one who creates moths.
