From the article, "Every moment in Lightning Returns is timed. Lightning is the savior, and must save as many souls as possible before the world ends. This also serves to extend the time the world has left with 13, perhaps even 14 if you play it right, days left since the prayers and thanks from aided people help feed Yggdrasil. Yes, that means Lightning Returns is also basically a Valkyrie Profile game, but we’ll get into that some other time.
It means that every moment counts."
