Explore a quiet archive through visible sonar signals. Reflect the returning light, remember the path, recover each fragment, and bring it home across five authored chambers. No enemies, timer, or audio-only clues.

Arrows / WASD move. Space sends a pulse. I / J / K / L aim. Z undoes; R resets. SONAR aims; MOVE walks. Adjacent map cells can also be clicked or tapped. Sound is optional and starts off.

Free browser game by KRYVOLT Games. RC1 (2026-10-09). Local progress stays on your device; no network telemetry.
