Instructions
Sonar Sweep
Hidden subs, a limited stock of depth charges and one clue per drop: every miss pings how many squares away the nearest sub is. Triangulate the fleet, sink it, and bank the charges you save.

Every run starts on the title screen. Pause any time with P or the pause button; calm mode removes flashes and screen shake.
Maker’s note
Each sunk sub pays 100 plus 25 for every charge still in the hold, and spare charges carry into the next, bigger sea. The fleet layout comes from a seed, so a daily run is the same sea for everyone.
