Confirmed
- The Shade System is for solo play.
- It creates magical copies of your mouse.
- Copies assist with puzzles and interact with the world.
- It exists so “every part of the journey remains open” without other players.

How to use it
- When a puzzle has two switches, two pressure plates or two paths, try summoning a Shade copy.
- Place a copy on one interactable and take the mouse to the other.
- If a copy disappears, look for a duration limit or a range limit; the game does not publish either.
What is not published
- Maximum number of copies.
- Duration / cooldown.
- Whether copies can carry objects.
- Whether the Shade System is available in the demo (the demo coverage mentions it, but not every full-game rule is guaranteed).
