Gustling in play: a paper kite riding a downward gust between rock spires under a purple night sky

What it solves

The gap

Endless arcade games feel unfair when a course can generate an impossible gap, and tuning speed and difficulty by playing is slow.

What it is

A finished, tested one-button flyer whose courses are always flyable, proven by an autopilot, with its feel in one config file.

How you use it

Unzip, run npm ci and npm run dev, then edit src/game.config.ts; npm test checks the game again in seconds.

Source code of a real, playable game to reskin and learn from, with its proofs built into the tests.

Who it is for

Use it when

  • Publishing your own one-button game (a paper boat, a firefly cave, a jetpack courier) on itch.io, web portals or your site.
  • Learning deterministic simulation, seeded generation and autopilot testing in TypeScript.
  • Building a branded arcade game for a client or a campaign.

Built for

  • Web and indie game developers who know some TypeScript.
  • Studios and freelancers who make branded browser games.

What you get

One config file

Title, logo, save key, flight physics, scoring, the difficulty curve over time, medals, kites and their unlocks, colours and sound.

Fair by proof

Every course is built around a safe corridor, and an autopilot flies 90 seeds on every npm test, so a change that makes the game unfair fails at once.

A finished game

Hold to climb, sparks and a x4 multiplier, graze points, gusts, crows and storms, a daily run, medals and kites, instant restart, best scores saved.

Tests and a guide

27 unit tests and Playwright browser runs, a size budget, an upload zip for itch.io or any static host, and a guide with reskin ideas and a tuning table.
