Echolume - Sound & Light

You are a small blind creature of the deep, and you move the only way you know how: by singing into the dark and riding your own echo.

Every tap is a song. It pushes you through the water, and for a moment, it lights the world: cave walls bloom in cyan, amber motes glitter, and things you would rather not meet are picked out in violet. But the deep listens back. Hunters swim toward the last place you sang. Sing to see; glide to survive.

ECHOLUME is a one-thumb atmosphere game about voice, light, and restraint.

• Two verbs, one thumb. Tap to sing: your song moves you, reveals the cave, and makes noise, all at once. Hold to throw your voice: the song blooms where you aim, and the dark turns toward it instead of you. • 50 handcrafted depths across four chapters, teaching the deep one danger at a time: thorn urchins, listening hunters, rivers that run upstream, false lights that bite, silence that swallows songs, ice that tells on you, and four bosses waiting at the gates. • The Abyss: an endless descent that is never the same twice. How far will you dare to sing? • Earn three stars per depth: reach the vent, spend your songs sparingly, and gather every mote. Light carries down with you, and every seventh depth is a gate that asks what you brought. • A living soundscape, synthesized in real time: your motes build melodies, the cave echoes your voice, and your own heartbeat warns you what is near. • Beautiful bioluminescent world rendered at 60fps. • Free to play, all 50 depths. Ads appear only after you clear a depth, never when you fail one, and a one-time purchase removes them for good. Optional Game Center leaderboard and 15 depth achievements for the Abyss. Haptics, reduced-motion, and high-contrast options included.

The deep is dark. You are not.
