Lighthouse

You are the keeper of a small island lighthouse. When night falls, boats pass in the dark — sweep your beam across the sea and hold it on them long enough to guide them home. Each guided boat docks at dawn and pays in coins, wood and oil. Upgrade your beam, your tank and your dock, decorate your islet, and climb the keeper's career across four ever-harsher lighthouses. Nightly triage: boats arrive in waves and guidance fades outside the beam — you can't save everyone. Fog shortens your light, storms hurry the boats, and both pay better. Daily contracts from the harbourmaster, a logbook of grateful captains, 13 achievements, and a certain secret visitor. The lighthouse keeps working while you're away.
