You are a small creature lost in a pitch-black cave. Press SPACE to emit a ping: the sound wave expands outward and briefly lights up the walls it touches. When a wave crosses the exit you hear a chime — panned toward it, louder the closer you are. Navigate by memory and by ear.
From level 2 onward something else lives in the cave. It is blind too, but it hears your pings through the rock — and it comes looking. Pings reveal it only as a snapshot of where it was.
