There's a main story? What is it? How do I finish it?!?
You meet the Leaders of each Kingdom and the Angels.
(edit: Normally they would have a big chance of visiting you once you played for long enough, ex 15, 30, or 50 Days)
But one of them was incorrectly written, which for most people blocks most of the Story Dialogs from happening.
A small fix update will be Released this month, which also includes a System which fixes Save files that have this Soft lock.
