Ping the dark. Find your way home.

THE QUICK GUIDE

How to play

Choose an unlocked dive in Coral Archive, Sunken Observatory or Midnight Trench. Nearby water is always visible. Ping reveals a larger circle for six moves, and explored locations stay faintly mapped.
Collect all three signal fragments, then enter the dock with oxygen remaining. Each accepted movement costs one oxygen; walls reject movement for free. Pausing, thinking and sonar consume no oxygen.
Arrow currents push one extra tile without another base oxygen cost. They stop at walls and never chain. Orange-spined urchins and corrupted red crystals cost three extra oxygen on contact. One-use vents restore one sonar charge when your battery has room.
Each fragment earns 100 points. A successful extraction adds 500, ten per oxygen remaining, and fifty per unused initial Ping. Each hazard contact subtracts 100; scores cannot go below zero. No extraction bonuses on defeat.
Finish within the displayed stronger move target without hazards for three stars, or the relaxed move target for two. Any successful return earns one. Wins unlock the next dive; replay to improve best moves, score and stars.

Swipe once or use the four direction buttons to move one tile. Keyboard: WASD/Arrow keys, Space for Ping, P/Escape for pause and M for sound. Thinking uses no oxygen.

Unlocked dives, best successful scores, stars, fewest moves and sound preference save locally when storage is available. Active dives reset on refresh. Hidden tabs pause movement and sonar until explicit Resume. No online leaderboard.
