+## Project Overview
+
+### Vision
+Neural Nexus is a modern HTML5 puzzle game that challenges players to connect neural network nodes in specific patterns. We're building an engaging, visually appealing game that combines contemporary themes with accessible gameplay mechanics.
+
+### Goals
+- **Primary:** Create a polished, addictive puzzle game with 50+ levels
+- **Secondary:** Achieve smooth 60fps performance across all modern devices
+- **Success Metrics:** 
+  - 5+ minute average session time
+  - 80%+ level completion rate for first 10 levels
+  - <3 second load time on mobile devices
+
+### Target Users
+- **Primary Users:** Casual puzzle game players aged 16-45
+- **Use Cases:** Quick gaming sessions, brain training, stress relief
+- **User Needs:** Engaging mental challenge without complexity overload
+
+## Architecture
+
+### System Design

+```
+
+### Component Relationships
+- **Game State:** Central store for level progress, score, timer
+- **Rendering:** Canvas-based with CSS for UI overlays
+- **Input System:** Unified mouse/touch handling for connections
+- **Game Objects:** Node and Connection classes with physics
+
+### Design Decisions
+| Decision | Choice | Rationale |
+|----------|--------|-----------|
+| Graphics API | Canvas 2D | Excellent performance, wide compatibility, simpler than WebGL |
+| State Management | Single Global Object | Sufficient for game scope, easy debugging |
+| Input Handling | Event-based | Responsive feel, works across devices |
+| Styling | CSS + Canvas | Leverage CSS for UI, Canvas for game graphics |
+
+## Technology Stack
+
+### Core Technologies
+- **Frontend:** Vanilla HTML5, JavaScript ES6+, CSS3
+- **Graphics:** Canvas 2D API with CSS animations
+- **Architecture:** Object-oriented game components
+- **Storage:** LocalStorage for save data and preferences
+
+### Key Libraries
+```json
+{
+  "dependencies": {
+    "No external dependencies": "Vanilla JS for maximum performance and control"
+  }
+}
+```
+
+### Development Tools
+- **Browser DevTools:** Performance profiling and debugging
+- **Testing:** Manual testing across browsers and devices
+- **Version Control:** Git with feature branching
+- **Performance:** Lighthouse for optimization audits
+
+## Game Design Guidelines
+
+### Core Mechanics Principles
+1. **Clarity:** Player immediately understands connection system
+2. **Progressive Difficulty:** Each level introduces manageable challenge increase
+3. **Feedback:** Visual and audio cues for all player actions
+4. **Flow State:** Difficulty curve maintains engagement without frustration
+
+### Level Design Standards
+```javascript
+// Level generation guidelines
+const levelDesign = {
+  nodes: {
+    minimum: 3,
+    maximum: 12,
+    progression: "gradual increase with occasional easier levels"
+  },
+  connections: {
+    formula: "nodeCount - 1 + Math.floor(level / 3)",
+    maxComplexity: "avoid overly complex patterns"
+  },
+  timing: {
+    baseTime: 60,
+    adjustment: "decrease by 2 seconds every 3 levels",
+    minimum: 30
+  }
+};
+```
+
+### Visual Design Patterns
+```css
+/* Color scheme consistency */
+:root {
+  --primary-cyan: #00d4ff;
+  --secondary-magenta: #ff00ff;
+  --success-green: #00ff64;
+  --warning-orange: #ff6400;
+  --background-dark: #0a0a0a;
+  --surface-glass: rgba(255, 255, 255, 0.1);
+}
+```
+
+## Performance Guidelines
+
+### Target Metrics
+- **Frame Rate:** 60fps on desktop, 30fps+ on mobile
+- **Load Time:** <3 seconds on 3G connection
+- **Memory Usage:** <50MB on mobile devices
+- **Bundle Size:** <1MB total (including assets)
+
+### Optimization Techniques
+
+1. **Rendering Optimization**
+   ```javascript
+   // Efficient canvas clearing
+   function clearCanvas() {
+     ctx.clearRect(0, 0, canvas.width, canvas.height);
+     // Better than: ctx.fillRect() for transparency
+   }
+
+   // Object pooling for particles
+   class ParticlePool {
+     constructor(size = 100) {
+       this.pool = [];
+       this.active = [];
+       for (let i = 0; i < size; i++) {
+         this.pool.push(new Particle());
+       }
+     }
+     
+     acquire() {
+       return this.pool.pop() || new Particle();
+     }
+     
+     release(particle) {
+       particle.reset();
+       this.pool.push(particle);
+     }
+   }
+   ```
+

+
+## Troubleshooting
+
+### Common Development Issues
+
+#### Performance Problems
+**Problem:** Game running slowly, stuttering animations
+```javascript
+// Debug: Check frame time
+function debugFrameTime() {
+  const times = [];
+  let lastTime = performance.now();
+  
+  function measureFrame() {
+    const now = performance.now();
+    times.push(now - lastTime);
+    lastTime = now;
+    
+    if (times.length > 60) {
+      const avg = times.reduce((a, b) => a + b) / times.length;
+      console.log(`Average frame time: ${avg.toFixed(2)}ms`);
+      times.length = 0;
+    }
+    
+    requestAnimationFrame(measureFrame);
+  }
+  
+  measureFrame();
+}
+```
+
+**Solutions:**
+- Reduce particle count
+- Optimize drawing operations
+- Use `requestAnimationFrame` properly
+- Check for memory leaks
+
+#### Touch Controls Not Working
+**Problem:** Mobile touch events not registering properly
+```javascript
+// Solution: Prevent default touch behavior
+canvas.addEventListener('touchstart', (e) => {
+  e.preventDefault(); // Prevent scrolling
+  // Handle touch
+}, { passive: false });
+
+canvas.addEventListener('touchmove', (e) => {
+  e.preventDefault(); // Prevent scrolling
+  // Handle drag
+}, { passive: false });
+```
