Tidewick

Tidewick is a calm idle game that ends. On a bare rock in a grey sea, gather driftwood from the tideline, hire beachcombers, cut stone, saw planks, build a harbour and a row of cottages, press kelp into lamp oil and send boats to the far banks. Raise the tower stone by stone, and when the lamp is full, light it so the ships can find their way home. Every purchase adds something you can see on the little island, the sky turns from day to dusk to night, and after about half an hour the lamp is lit and the game tells you how long it took.
