Hint 2 — the useful arrangement

Reveal solution / story details

The boulder extends the place you can stand north of the mirror. It does not need to make a full bridge to the exit.

Full solution and gameplay

Reveal solution / story details

Check the reflection before jumping. The stone’s useful position is directly beyond the northern shore on the mirror’s column.

The clip under the last step is the same room in the released game: Retail puzzle 4 in Game Guides Channel’s October 12, 2026 recording, which follows this route to the exit.

  1. Push the mirror right along the causeway to the eastern bend. Leave it aligned with the northward stretch of land.
  2. Walk around to the boulder. Move it onto the northern lip of the island in the same column as the mirror.
  3. Push the boulder north into the water, then stand on the resulting stone. This extra distance puts the reflection on the southern tip of the western island.
  4. Activate the mirror action to jump west. Walk north along the exit island to the yellow ring.
