Why This Recommendation Makes Sense
Opening route, then parallel major routes, then late game, then the ending. This page only recommends an objective when the progression dependencies support it.
Opening route: release the Opening Key, run its five stations, then place it at the Drawbridge. That opens the wider island.
Four parallel major routes
They are shown side by side because none of them comes first. Each one opens a different landmark.
Opening route — places its key at the Drawbridge and releases the four route keys

Late game — Black Tower, then the ending
We never claim a mandatory order between the coloured routes, because the game does not have one.
Late game: the Black Tower reward is the Ending Key. It arrives already finished, so it has no cutter route.
Ending: place the Ending Key at the Ending plinth, open the Ending Gate, then finish the ending sequence.
Post-game: the Overflow route and the completion layers, tracked separately from the main route.
A nearby puzzle is never promoted to a required step. Optional content is listed separately, and only when it sits near the step above.
Why Am I Stuck?
Pick the line that matches your run. If the objective is already done and something still will not run, the fault is in that system rather than in your progression.
- I do not know what to do next
- I know what to do, but I cannot find it
- A system will not activate
- A puzzle will not complete
- My Big Key will not cut or place
- I finished the main ending
- I am missing things for 100%
A specific system still will not run
The key is already where it belongs on these, so what is left is clearing the system itself.

What Next Questions
What should I do first in Big Walk?
Start with the opening challenge loop. Finish the first key route, place the key at the Drawbridge, and the wider island opens.
Opening stage →What should I do after the Drawbridge?
Work a major route. The Red route opens the Map Room, and Green, Blue and Yellow open the Chairlift, the Train and the Tunnels.
Red route stage →Do I have to do the coloured routes in order?
No. They are parallel routes with different destinations, and this page never treats them as chapters. Work whichever one your run leaves open.
Coloured routes →What should I do after finishing a route?
Follow that route to its destination, then continue any other route that is still reachable. The result above names the one to pick up.
Main progression →The page says my route is done but something will not run. Why?
A placed key whose destination is not running is a system problem, not a progression blocker. This page hands it to that system’s own page instead of sending you to another station.
Troubleshooting →What should I do after the main ending?
Big Goodbye ends the main route. The post-game route, the second ending and completion work continue from there as separate goals.
