Windpost

Windpost is a free hot air balloon game for the web browser, made by Toyjar. The balloon can't steer, only rise and sink, so you change direction by changing height: the sky has layers of wind (3 in spring, 5 by winter), each blowing its own way. Ride them to deliver 21 letters across 4 seasons on a tiny planet. One button; a full year takes about 10 minutes, on a phone, tablet or computer.

In Windpost you hold to fire the burner and rise, and let go to sink. You can't steer, but each layer of wind blows its own way, so change height to change direction. Drift low over a house's ring to drop its letter; aim for the bullseye. Letters refill fuel; land on empty and the run ends. Fire the burner: Hold the mouse, Space, ↑, W or Enter (desktop) / Hold anywhere on screen (phone); Sink: Let go (desktop) / Lift your finger (phone).

Windpost is played in 5–10-minute runs. Start any time, stop any time.

In Windpost you steer by changing height. Each layer of wind blows toward its own compass heading, faster the higher up, so climb or sink into another and you drift with it. Altimeter arrows show each layer's direction, and the one heading for your letter glows; paper cranes and clouds drift with their layer too. The winds slowly shift within a season, so routes can't be learned by heart.

A run of Windpost is one year of 4 seasons. Spring · Morning: 3 layers of wind, paper cranes and first-flight tips (4 letters). Summer · Noon: a fourth, higher wind and thermals that save fuel (5). Autumn · Dusk: thunderclouds, falling leaves and a mid-season turn of the winds (6). Winter · Night: the jet stream up top, lanterns, snow and the aurora (6). Counts include the golden letter.

In Windpost the season's letter is the golden last letter of each season, for its landmark: Blossom Mill in spring, Cape Lighthouse in summer, Summit Pagoda in autumn, the Polar Tree Post Office in winter. It appears once the others are delivered, and they lead you its way. Deliver it and the next season's colours sweep the planet; it refuels you, and leftover fuel becomes bonus points.

In Windpost the burner and its pilot flame both use fuel. Deliveries refill it, more for an accurate drop, and cranes add a little. Bumps and lightning strikes cost fuel and break your streak but don't end the run. On an empty tank you can't fire the burner: the balloon sinks, and 1.5 seconds after it lands the run is over. A letter delivered on the way down still counts and refuels you.

In Windpost the closer a letter lands to the bullseye, the better its postmark: Delivered, Precise or Bullseye, worth 1×, 1.5× or 2.5× its 100 points, plus up to 100 for a delivery within 40 seconds. Deliveries in a row without a bump lift your Tailwind to ×3, and the music grows with it. Season's letters start at 500, paper cranes give 20, and leftover fuel scores at each season's end.

Yes. In Windpost, delivering winter's golden letter completes A year of winds: the four seasons' colours flash across the planet and a flock of paper cranes takes off. Then you can choose Fly into year 2. The seasons start again from spring with faster winds, thunderclouds from the start and less fuel per delivery, and it's all about the score. Each year after that gets a little harder.

Yes. When a run of Windpost ends, tap Keep a postcard on the results to make one: the whole planet with your route traced across it on the left, and on the right a handwritten note of your letters and bullseyes, your score, a season stamp and a postmark. Long-press or right-click to save it; on devices that support sharing you can share it directly.

Windpost keeps your best score, the total number of letters you've delivered and your sound and language settings in your browser on this device. Nothing is sent to a server, so clearing the browser's site data resets them. Every run starts again in spring.

Windpost is available in Chinese, English, Japanese, and Korean.
