From the README

A dependency-free, single-file Flappy Bird clone for the browser, built with the pi coding agent — plus a deterministic Playwright browser-test suite and a CI coverage gate.

Or just open flappy.html directly in a browser.

Deterministic Playwright browser tests drive the real page in a real browser — no mocks. The game exposes an automation API (window.__flappy) and a test mode (window.__FLAPPY_TEST__) that freezes the animation loop so tests can step the simulation in fixed time slices.
