Platform constraints and optimization principles.

---

1. Platform Considerations

Key Constraints

Constraint	Strategy
Touch input	Large hit areas, gestures
Battery	Limit CPU/GPU usage
Thermal	Throttle when hot
Screen size	Responsive UI
Interruptions	Pause on background

---

2. Touch Input Principles

Touch vs Controller

Touch	Desktop/Console
Imprecise	Precise
Occludes screen	No occlusion
Limited buttons	Many buttons
Gestures available	Buttons/sticks

Best Practices

• Minimum touch target: 44x44 points
• Visual feedback on touch
• Avoid precise timing requirements
• Support both portrait and landscape

3. Performance Targets

Thermal Management

Action	Trigger
Reduce quality	Device warm
Limit FPS	Device hot
Pause effects	Critical temp

Battery Optimization

• 30 FPS often sufficient
• Sleep when paused
• Minimize GPS/network
• Dark mode saves OLED battery

6. Anti-Patterns

❌ Don't	✅ Do
Desktop controls on mobile	Design for touch
