How to solve the optics lab
Charge before receiving
The beam must pass through every gold crystal before entering the bottom receiver. A shortcut that misses a crystal does not clear the chamber.
Ignore decoys
Later chambers add mirrors away from the intended route. Rotate only what the beam can reach, and save the three-move assist for a real dead end.
