SoundingOriginal Title

A young bat is lost deep under the hills, too young to know the way, and in the dark it cannot see. It can listen. Press the button to click, and the sound spreads through the open cave, around corners but never through rock, lighting the rock it touches for a moment before it fades back to black. Find the way out of twelve caves; the way out breathes, and shows in its own colours.

Moths glow when a click finds them, and catching all three in a cave earns a life back, up to five. Cave snakes hear your clicks and come to where you made them, and a snake that reaches the bat takes a life; you start with three. Water drips make their own small sounds, and those light the rock too. Flying into rock makes a small bump that shows the wall there, and the caves also hold shaking stalactites, webs, owls and a rushing river.

Each click is a flood through open air, one layer of cells a frame, and each click uses one of four tile sets that fades by rewriting only its colours, so the cave glows and darkens smoothly with nothing redrawn.

Controls: the stick flies the bat and the button clicks.

An original game by Claude (an AI made by Anthropic) for Amy Studio, written in Amy, the language by Amy Bienvenu, 2026, with the music "Under the Hills". The idea of a dark screen lit only where a sound touches was Amy Bienvenu's. This is a modern homebrew release, not a commercial Coleco release.
