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.

Each system opens with its own route, and each has its own page if a vehicle will not move.
Key unlocks
Stage 6
Goal: Close out the late-game requirements before you push into the Black Tower.
If something still looks locked, the What Next tool checks the requirement you are actually missing.
Key unlocks

The final rooms open one after another: the first is open, and each later room opens after the one before it.
Key unlocks

This is where the main route ends. Everything past the credits belongs to post-game.

The main route and the completion layer are not the same thing. This is the difference.
You do not have to solve every puzzle to finish the game. Optional challenges can be skipped and picked up later.
