The Windows and Mac versions of Nevermind use biofeedback technology to detect your feelings of stress while playing. When you start to become scared or anxious, the game will dynamically respond to those feelings, which in turn directly affects gameplay.
Although the biofeedback element makes for a completely unique experience, you can always play Nevermind without ANY biofeedback hardware and still have a great time. Flying Mollusk is always working toward supporting new and additional technology. Please refer to our tech page for the most up-to-date list of supported technologies.
XBOX ONE: The Xbox One edition of Nevermind is not capable of detecting and responding to biofeedback. While there are no biofeedback features available in the Xbox One version, the same adventure puzzle gameplay is fully available.
