Echo Harbor. The dock light stays on, day and night.

The harbor

Twelve years of waiting mail

Twelve years ago, Echo Harbor’s previous courier went out with the mail and never came back. Since then the mail has piled up, and hardly anyone makes the trip.

Now the Postal Service has sent you.

— the Postal Service

Why does the Greenhouse go dark at 19:40? And where is that knock coming from? Short, short, long.

a small harbor, a few people:

Luna
Runs the post office and keeps the dock light on, day and night.
Milo
Can fix almost anything, but he and Hazel haven’t spoken in years.
Hazel
Keeps the Greenhouse, which goes dark at the same minute every night.
Kai
Captains the Longwing, and only runs out this far when the Postal Service pays.

How a delivery goes

Every delivery is a small route puzzle that takes a few minutes. Stop at any moment and pick up exactly where you left off.

Draw the whole route first

Plan the trip on a grid, one cell at a time. Drag back to erase part of it, and redraw as often as you like.
Then watch the mail cart go

Tap Go and the cart makes its rounds. Pass the right door and the letter is delivered. Anything that can’t be delivered comes back.
Residents keep their own hours

Each resident is home only at certain hours, and the home bar under a door shows when. Time only passes when your cart moves or waits, so there are no timers and no fail screens.
Every delivery changes the harbor

The workshop lights up again. A mailbox flag goes up. Everything you bring leaves its mark, and it’s still there the next time you open the game.

Easy to pick up, easy to put down

Version 1.0

Part One: There’s Mail for You

The prologue and the first two chapters, about 40 to 60 minutes of story. It answers why the Greenhouse goes dark and where the knock comes from, and ends on a quiet night, with the harbor lit again. After that, the harbor stays open: the pigeonhole still has mail to deliver, and new delivery jobs keep coming.

More chapters will follow in future updates.
