Harbor Light: Storm Watch

You keep the light on a rocky coast, and the fleet is coming home in the dark.

Sweep the beam across the ships: in the light they can see the rocks and follow the safe channel into the harbor. Leave one in the dark too long and its captain is lost, steering straight for home with the tide pushing, whatever is in the way.

• One finger aims the lamp. The lens is heavy, so plan your sweep.
• Ration the oil. The lamp burns all night; supply boats bring more.
• Sound the foghorn to guide every boat near the lighthouse, even the ones you can't see.
• Fire flares to light a patch of sea for a boat the beam can't reach in time.
• Sweep fast across several boats in one pass for a chain, or hold steady to fill a ring.
• Crews in the water and boats with failed engines: find them with the light, then guide the lifeboat out and hold the light while the crew are hauled aboard.
• Smugglers run with no lights. Catch one in the beam for a bounty.
• Spend the coins each night earns on lighthouse upgrades: a wider lens, faster gearing, more flares.
• Fishing boats turn fast, freighters slow (and count for three), supply boats carry your oil.
• The North Coast, free: thirteen nights, from a calm first watch through fog, a gale, rocks that cast shadows, mirror buoys, busy harbor traffic and a clockwork you set yourself.
• Towns that glow through the night and harbors where the boats you bring home tie up.
• Hold until dawn and the whole coast lights up.
• Recorded surf, wind, rain and thunder that change with the weather. No account, no ads.

The Keeper's Pass, one purchase, yours to keep:
• The Ice Coast: six winter nights in a fjord where icebergs drift across the approaches and snow squalls cut the beam.
• The Long Night: no dawn, the boats come faster and the weather worsens. How long can you last?
• The Daily Coast: a new night every day, the same for every keeper. Keep your streak going.
