The whole main route, from the opening area to Big Goodbye. The opening and the main gates are fixed, but the middle of the game is not, so this shows the milestones and what each one unlocks instead of a fake puzzle-by-puzzle order.

You do not have to solve every puzzle to finish the game. Optional challenges can be skipped and picked up later.
