Scored 41 for a clear but purely informational reference guide documenting standard 2D game development conventions. Low score because it automates nothing, description is too brief to trigger, and Claude likely already knows these principles. Could be improved with framework-specific patterns or actual implementation examples.

# 2D Game Development
> Principles for 2D game systems.
---
## 1. Sprite Systems
### Sprite Organization
| Component | Purpose |
|-----------|---------|
| **Atlas** | Combine textures, reduce draw calls |
| **Animation** | Frame sequences |
| **Pivot** | Rotation/scale origin |
| **Layering** | Z-order control |
### Animation Principles
- Frame rate: 8-24 FPS typical
- Squash and stretch for impact
- Anticipation before action
- Follow-through after action
---
## 2. Tilemap Design
### Tile Considerations
| Factor | Recommendation |
|--------|----------------|
| **Size** | 16x16, 32x32, 64x64 |
| **Auto-tiling** | Use for terrain |
| **Collision** | Simplified shapes |
### Layers
| Layer | Content |
|-------|---------|
| Background | Non-interactive scenery |
| Terrain | Walkable ground |
| Props | Interactive objects |
| Foreground | Parallax overlay |
---
## 3. 2D Physics
### Collision Shapes
| Shape | Use Case |
|-------|----------|
| Box | Rectangular objects |
| Circle | Balls, rounded |
| Capsule | Characters |
| Polygon | Complex shapes |
### Physics Considerations
- Pixel-perfect vs physics-based
- Fixed timestep for consistency
- Layers for filtering
---
## 4. Camera Systems
### Camera Types
| Type | Use |
|------|-----|
| **Follow** | Track player |
| **Look-ahead** | Anticipate movement |
| **Multi-target** | Two-player |
| **Room-based** | Metroidvania |
### Screen Shake
- Short duration (50-200ms)
- Diminishing intensity
- Use sparingly
---
## 5. Genre Patterns
### Platformer
- Coyote time (leniency after edge)
- Jump buffering
- Variable jump height
### Top-down
- 8-directional or free movement
- Aim-based or auto-aim
- Consider rotation or not
---
## 6. Anti-Patterns
| ❌ Don't | ✅ Do |
|----------|-------|
| Separate textures | Use atlases |
| Complex collision shapes | Simplified collision |
| Jittery camera | Smooth following |
| Pixel-perfect on physics | Choose one approach |
---
> **Remember:** 2D is about clarity. Every pixel should communicate.
