## Implementation Review
### Code Quality Checks
✅ **Direction Calculation Algorithm**
- 2x threshold prevents flickering
- Handles all 8 directions correctly
- Edge cases handled (zero distance)
- Performance: O(1) calculation
✅ **Animation Integration**
- Idle animations for all 8 directions
- FlipX support for left-facing
- Graceful fallback if animation missing
- Change detection prevents redundant plays
✅ **Distance-Based Activation**
- Squared distance for performance
- Configurable range (default 96px)
- Only updates when in range
- Smooth transitions
