A bat glides automatically through a moonlit cavern. Hold to rise, release to sink, and thread gaps between stalactites and stalagmites. Grab fireflies and moths for points, skim rocks for risk bonuses, and one collision ends the flight instantly. Tighter tunnels, moving spikes, and wind pulses raise the difficulty as distance grows. One-thumb flappy controls keep the rules crystal clear while every meter feels tense and readable—ideal for chasing personal bests in short, pulse-raising runs.
