Cave Echo Puzzle

Cave Echo Puzzle is a sound-navigation puzzle game set in absolute underground darkness. You cannot see the cave — only echoes reveal what lies ahead. Tune between low, mid, and high frequencies to detect walls, deadly pits, resonance crystals, and the golden exit. Each chamber challenges your echo budget, movement efficiency, and ability to read returning sound ripples. Twelve handcrafted levels, crystal-powered echo bonuses, star ratings, achievements, and deep cave lore make this a uniquely sensory maze experience unlike any grid puzzle before it.
