Audit and improve the visual design, polish, and player experience of an existing game. Use when the user says "make my game look better", "improve the design", "add polish", "add juice", "add particles", "fix the UI", or "make it more visually appealing". Do NOT use for gameplay logic changes (use

Performance Notes Take your time to do this thoroughly Quality is more important than speed Do not skip validation steps Design Game Run a UI/UX design pass on an existing game to improve visuals, atmosphere, and game feel. No design experience needed — this command analyzes your game and applies proven visual patterns. Instructions Analyze the game at $ARGUMENTS (or the current directory if no path given). First, load the game designer skill to get the full design vocabulary and patterns. Step 1: Audit Read package.json to identify the engine Read src/core/Constants.js for the current color palette and config Read all scene files to understand current visuals Read entity files to see how game objects are drawn Read src/core/EventBus.js for existing events Step 2: Design Report Score each area 1 5 and present as a table: Area Score Notes Background & Atmosphere Color Palette Animations & Tweens Particle Effects Screen Transitions Typography Game Feel / Juice Game Over Expression Usage If personality characters exist, score how reactively expressions change to game events. Score 1 if expressions never change. Then list the top improvements ranked by visual impact, with a plain English description of what each one does (e.g., "Add a sky gradient so the background looks like a real sky instead of a flat color"). Step 3: Implement Ask the user which improvements they want, or implement all if they say so. Follow the game designer skill patterns: 1. All new values in Constants.js 2. Use EventBus for triggering effects 3. Don't alter gameplay (physics, scoring, controls, spawn timing) 4. Prefer procedural graphics 5. New files in proper directories Step 4: Verify Run npm run build to confirm no errors Summarize all changes made in plain English Example Usage Full design pass Result: Audits visuals → scores Background 2/5, Particles 1/5, Typography 3/5 → adds sky gradient background, star parallax, explosion particles on asteroid destroy, screen shake on hit, smooth scene transitions. All values in Constants.js. Troubleshooting Visual changes cause performance drops Cause: Too many particle emitters or gradient fills per frame. Fix: Limit active particles (pool and reuse). Use cached gradient textures instead of recreating per frame. Design changes break layout on different screen sizes Cause: Hardcoded pixel positions instead of using PX scale factor. Fix: All positions and sizes should use Constants.js PX relative values. Next Step Tell the user: Your game looks much better now! Next, run /game creator:add audio to add chiptune background music and retro sound effects — all procedurally generated, no audio files needed. Pipeline progress: ~~/viral game~~ → ~~/design game~~ → /add audio → /qa game → /review game (This is the /viral game one shot pipeline — not the /make game multi session, milestone driven workflow.)
