Game Qa

This is a comprehensive QA automation skill for browser games built on Playwright. It covers visual regression testing, gameplay verification, performance checks, and accessibility audits. The skill is thorough about testability requirements: your game needs to expose state via `window.__GAME__` and implement `render_game_to_text()` so tests can inspect what's happening without parsing pixels. It includes patterns for deterministic testing with seeded randomness, frame-precise clock control, and seven core gameplay invariants like scoring and death states. The documentation is dense but practical, with ready-to-use config templates and fixture code. Use this when you need to add automated testing to a Phaser or Three.js game, or when debugging flaky game tests that depend on timing or visual state.
