Echo: Labyrinth in the Dark

You find yourself in a labyrinth hidden in complete darkness. Tap to release an echolocation wave: it will reveal the walls for a few seconds and then leave you alone with your memory again. Find the exit, don't crash into the walls, and try to use as few pulses as possible. Four difficulty modes, growing labyrinths, level series, points, and a leaderboard await you. Coins are awarded for completion — unlock new wave colors and effects. Progress and records are saved.
