Crosswind Isles: An Arcade Flight Sim Over Islands

Fly a little prop plane over procedural islands, in one small offline HTML file: take off under a callsign, run a 12-gate course or a full mission, and line up the ILS cross-needles for a judged landing. Live wind and weather, real cloud immersion, moving AI traffic, three camera views and a career logbook. Procedural terrain, ocean, sky and synthesized audio.

Crosswind Isles: An Arcade Flight Sim Over Islands

Bring the islands and routes, the plane handling and the scoring, and optionally the weather set, traffic, camera views and the UI text. The Skill returns a downloadable Skill (the flight-sim project, a customize guide, headless verification) and one playable example flight.

How it works

  1. Your coding agent copies the working game and follows the customize guide: flight model, the gate course and missions, the ILS landing judge, the map and logbook, and the synth audio.

  2. The published example is the full loop: a callsign takeoff, a 12-gate course or a full mission, cloud immersion, AI traffic in the pattern and a judged ILS landing written into a career logbook.

  3. The game is played headlessly under the sandbox policy: takeoff, a banked turn, the three cameras, weather and cloud immersion, the map, the logbook, a mission accept and a phone throttle.

Frequently asked questions

Does it call a model or need a key?

No. The Skill gives your agent a working game, a customize guide and verification; the game itself makes no network calls and calls no model.

Why is the demo sandboxed?

The frame has an opaque origin and no network access, so the scene can’t read anything from this page or reach the internet.

Is the game bilingual?

The page is bilingual; the game’s own UI text is in English.

What are the visuals and audio made of?

All of it is code: three.js terrain, ocean and moving sky, procedural aircraft and AI traffic, and WebAudio synthesis for the engine and ambience. No image, font or audio files ship with it.

Does it work on mobile?

Yes: throttle and steering are on-screen. Verified under touch emulation, not on real devices.

Why is there no online generation?

Building a new scene needs a model key inside the sandbox, which the backend doesn’t support yet. Run the Skill with your own agent for now.
