A deep-sea descent where sound is sight. Every sonar ping lights the pitch-black abyss in fading phosphorescence — and calls the blind hunters. Hide in sonar shadows, steal light from enemy pings, evolve at depth gates, and dive as deep as you dare.

Tips
Check the controls before starting; browser games often hide the best shortcut in plain sight.
On mobile, use page fullscreen first so browser chrome does not steal touch space.
On desktop, keyboard focus matters: click the game once before using movement keys.

Echo Abyss
A one-finger deep-sea sonar survival roguelite with no start screen. Pitch-black procedural caves are revealed only by expanding sonar wavefronts with SDF-raymarched soft sound-shadows (WebGL2 with full Canvas 2D fallback), a GPU plankton field that exists only where light touches, blind hunters that hear your every move, an anglerfish lure that punishes greed, erupting abyssal vents, a leviathan whose roar lights the whole map for everyone, 12 stackable evolutions at depth gates, fully synthesized WebAudio whose echo notes return at physically correct times and whose convolution reverb measures the cave around you, and a death screen that paints your entire dive as one luminous Afterglow thread. Score = depth + pearls × unharmed combo, submitted to the leaderboard.
