Thalweg

The Long Tide

You keep a lighthouse. Each season the water is a little further out and fewer ships come. Scroll, and watch the sea go.

A year, an hour a day

The Long Tide runs on your clock. Each real day is a day in the keeper's year, and the game only asks for an hour of it: trimming the lamp, logging the boats, walking down to where the waterline was yesterday. Miss a day and the log has a gap. That is allowed.

By autumn the boats are rare. By winter you are keeping the light for nobody, and the game does not tell you whether to stop.

Where the sea used to be

The seabed is the second half of the game. What the water leaves behind is walkable, and some of it was never meant to be found.
