PERIGEE
A free browser game from Core Systems Asset Factory. Genre: Simulation, Strategy. Free.
PERIGEE is a free browser game, free to play in the browser.
A settlement stands on a shelving coast. It wants water in some places and never in others, and it will not listen to you. You are not its god of harvests, only of tides. You set the moon's orbit, and everything the sea does follows from where the moon is. There is no direct power anywhere in this game: no building, no digging, no blessing, no smiting. One lever, and a coast that answers it.
Free, plays in the browser, about fifteen minutes for a full run of ten seasons. Your progress is saved after every season. The tide is real physics, and that is the whole design Tide-raising force falls off as the cube of distance. So bringing the moon close does not raise the tide a little; it raises it enormously.
Across the legal orbital range that is 0.13 m of amplitude at apogee against 1.47 m at perigee, out of one equation. Perigee is not a tuned power-up; it is an inverse cube doing the work. Three consequences you will feel in the first minute: The moon has weight. It answers slowly. A dive to perigee has to be started hours before the hour that needs it, and you will still be low when the water reaches the fields.
High water travels along the shore.
