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:
AreaScoreNotes
Background & Atmosphere
Color Palette
Animations & Tweens
Particle Effects
Screen Transitions
Typography
Game Feel / Juice
Game Over
Expression UsageIf 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

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.
