From the developer:
Lurking is a survival thriller game where sound is the only way you see. The game spawned from the core concept of using a microphone input device in a meaningful way for gameplay. This game is built on a system that upon calibration detects your breathing. This audio data is then converted into game visuals in the form of pulses, creating a secondary level of immersion.
