Echo Bat: Ping the Dark

Tilt your phone to fly a bat through an endless cave. Tap to dash and ping your sonar, because you only see what the ping lights up. Free, offline, no ads.

Echo Bat is an endless cave runner you steer by tilting your phone. You fly a bat through a dark cave, and you only see the walls where your sonar ping lands. Tap to dash and ping, dodge the rocks, and see how far you can fly. Free to play, works offline, no ads.

A bat. A cave that goes on forever. A sonar pulse you can fire to light the world. The cave shows itself only where the ping lands, and only for as long as the wave travels. The rest is shadow.

ENDLESS CAVERN A procedural cave that never ends. Every run threads new rock, new chambers and new biomes: Abyss blue, Ember orange, Void violet, Verdant green. Each has its own glow and atmosphere.

SONAR FLIGHT Pinging the dark is the whole loop. Every tap is a dash AND a sonar wave. Use them to dive-kill stinger enemies, smash crystals for points, and chain combos that stack up to 5x.

TILT-TO-STEER Native motion controls calibrated to your hold. After each crash the game resets neutral to your current pose, so you can shift posture between runs without losing the line.

BOSS ENCOUNTERS Every few kilometres a luminous cave guardian rises out of the dark. It pulses, fires hostile sonar rings, and only dies if you dash straight into it. Three pips. Two hits. One bat.
