So just finished up the main story-line. Kinda feels like we didn't solve the real problem. If the world required a rebirth and we stopped it, there-by meaning the world will just steadily decline into gradual nothing- Then are we really the good guys? I mean Kaguya is doing a killer dance in the credits and all, but I'm not sure that's going to help matters long-term. Maybe the post-game dungeon clears this up?
