Why this page is not a walkthrough
A named puzzle needs clues tied to a recognizable scene. Advice such as looking around or talking to friends does not establish that the writer knows this puzzle, so it is not presented as puzzle guidance.
Evidence still needed
Useful evidence would include released-build footage or screenshots, the platform and version, the scene that identifies the puzzle, the actions that change its state, and the confirmed outcome.
What to use instead
For verified setup help, use the multiplayer guide. For official accessibility help, the developer FAQ explains how a host can enable challenge skipping before a session.
