ConcertoNotes Game Playtest
Overview
Use this skill to test browser games the way players experience them: through boot, input, scene transitions, HUD readability, and visual state changes. Prefer browser automation and screenshot review when the project supports it.
Preferred Workflow
- Boot the game and confirm the first actionable screen.
- Exercise the main verbs.
- Capture screenshots from representative states.
- Check the UI layer independently from the render layer.
- Report findings in severity order with reproduction steps.
Tooling Guidance
- Prefer Playwright or equivalent browser automation already available in the repo.
- When the game is canvas or WebGL heavy, screenshots are mandatory because DOM assertions alone miss visual regressions.
- Use screenshots to judge playfield obstruction and HUD weight, not just correctness of text or layout.
- When deterministic automation is not practical, do a structured manual pass and capture evidence.
- For 3D rendering bugs or unexplained frame cost, use SpectorJS and browser performance tooling rather than guessing from code alone.
Common Checks
2D checks
- sprite alignment and baseline consistency
- hit or hurt animation readability
- HUD overlap with the playfield
- command menu state changes
- tile or platform readability
- input-state feedback and turn-state clarity
3D checks
- first-load playability versus dashboard-like chrome
- persistent overlay weight versus playfield visibility
- camera control and camera reset behavior
- pointer-lock or drag-look transitions when menus and overlays open
- depth readability and silhouette clarity
- secondary panels collapsed or dismissible during normal play
- resize behavior
- WebGL context loss or renderer fallback behavior
- material or lighting regressions
- GLB or texture streaming stalls
- collision proxy or physics mismatch
- performance cliffs tied to post-processing or asset load
Responsive and Browser Checks
- desktop and mobile viewport sanity
- safe-area and notch issues where relevant
- reduced-motion behavior for UI transitions
- keyboard, pointer, and pause-state handling
- React state and scene state synchronization when the project uses React Three Fiber
Reporting Standard
Lead with findings. Keep each finding concrete:
- what the user sees
- how to reproduce it
- why it matters
- what likely subsystem owns it
