The Tidal Courier

Welcome to Moonbay Isles.

In The Tidal Courier, you play as a young island postman sailing an old mailboat across a world shaped by the tides. Plan your routes, deliver letters, collect replies, and reconnect islands that have slowly drifted apart.

This is a calm, turn-based route-planning puzzle game with no time pressure. Study the map, predict changing tides, use ocean currents and island facilities, and decide the best order for every delivery.

Features:

• Plan routes across a changing tidal map
• Deliver ordinary letters, relay mail, return letters, tide-marked parcels, and more
• Use lighthouses, boatyards, teahouses, windmills, and floating bridges
• Choose from multiple boats with distinct sailing abilities
• Undo, retry, reset, and experiment freely
• Explore 72 handcrafted levels across six chapters
• Collect postcards, islander stories, and special postmarks
• Restore your own permanent Postman’s Island
• Take on deterministic Daily Charts
• Play offline with no account required

Some letters must wait for the tide. Some replies can only arrive by taking the long way around.

Set sail, follow the changing routes, and help every letter find its way home.
