Spoiler warning: The final puzzle involves a clockwork heart. In pre-2021 versions, you simply pulled the heart out. In v15.02.2021, you must use the Spectrometer to see the sin —a memory of Waldegrave locking a sentient elemental inside the heart. The tactile feedback when you unscrew the heart's valves is sickeningly realistic, courtesy of the haptic patch.
