The Fix: You cannot swap with a clone through blue light (blocks the soul swap), and you cannot create clones in red light (blocks the creation beam).
Walkthrough Tip for "Proper Piece" Puzzles:
The Setup: Find the source of the light.
The Strategy: You often have to create a clone in a safe zone, swap to it, and then manually move a block or switch to cut the light, allowing you to swap to the final "proper piece" (the target clone).
The "Impossible" Puzzle: If you are stuck in a room with 4 recorders/devices, the solution is usually to record yourself picking up a piece, swap to the clone, and have the "past" version hand you the item.
Ending B: The Duality (Neutral Ending)
How to get: Collect 6-11 Memory Fragments. During the final dialogue with your other self, choose "We are the same."
Outcome: You merge both realities. The world becomes a static, gray wasteland.
Bug fixed: The credits used to roll infinitely. Now you can skip after 30 seconds.
Chapter 2: The Twin Sanctuary (Puzzle Introduction)
Objective: Learn synchronized switches.
Walkthrough:
Enter the large hall. You will see a pressure plate in Primal, but the door is in Echo.
Solution: Stand on the plate in Primal. Without moving, shift to Echo. The plate stays pressed (because your body is anchored), but the door now exists. Walk through.
Fixed strategy: Do not step off the plate before shifting. Legacy guides told you to "quick-shift" – that caused a collision detection error. Now, the game correctly holds your position.
