About the game
Echo Bat is a flappy cave flight in total darkness. Tap to flap your little bat upward; let go and gravity pulls you down. The cave walls are invisible until you listen for them.
Hold down to send out sonar: rings spread from the bat and the walls flash up as glowing outlines that slowly fade. The catch is that while you hold, you are not flapping, so every look costs you height, and your echo meter drains as you use it. Fireflies drifting through the cave refill it. The first seconds are a warm-up where hitting a wall just bounces you back, then the light fades for real. Score is the distance you fly, plus five for every firefly.
