Moonpull

You are the moon over a tiny harbour, and the tide is yours to pull.

Fishing boats need high water to clear the sandbars and the reef. Villagers need low water to walk across the same sandbars. Everyone keeps their own timetable, so you raise and lower the sea at just the right moments. One drag is the whole game.

• 24 harbours, from a single ferry to three causeways, reefs and a crowded quay
• A daily harbour, new every day
• Three hearts per level: keep everyone safe for three stars
• A tide gauge that shows the safe tide when you want help (turn it off for a challenge)
• Plays in the browser on desktop and phones

Every level is checked by a solver: there is always a way to save everyone, and no single fixed tide will do it.
