Dark Echoes: Pulse

Dark Echo is a suspenseful puzzle game set in a pitch-black world. You can't see anything on the screen. You must send out a "Sound Wave" (Sonar) by tapping the screen to illuminate your surroundings and reveal walls. But be careful! Each sound wave drains your energy and can attract red "Hunters" hiding in the darkness. Trust your memory, plot your route, and reach the exit door before your energy runs out.
