If you've ever played, seen, or heard of Earthbound or the Mother game franchise (they're the same, but Mother 1-3 are in japan and Mother 2 is Earthbound in the US), this show as the exact same tone as that. It's got this fun and happy veneer on top of it, but right underneath there's some deep and dark subject matter that it touches on every now and then. Now I'm just waiting for the point where all that underneath is just brought front and center.
