I haven't finished a full playthrough yet, but I want to make sure I'm actually understanding the premise first. So, it seems like I continue reliving my life until I solve the puzzle and figure out how to make the world not end. (Haven't done this yet; I've solved some things, but not everything.) But I'm assuming the game doesn't end there, and at that point you figure out how you want your actual life to end in a somewhat more free choice style rather than finding the correct answers? Am I understanding that correctly?
