### 2.2 Charge System

| Charge Phase | Shooting Characteristics | Explanation |

|----------|--------------------------------|------|

| Light Charge | Slow bullet velocity, weak power, large deviation | Rapid fire, low hit rate |

| Medium Charge | Normal flight velocity, improved stability | Recommended stage, suitable for most targets |

| Full Charge | Maximum power, extremely accurate, triggers explosion/effects | High score stage, specific targets must be hit with full charge |

- **Display Method**: Charge progress bar + crosshair color change + sound effect feedback

---

### 2.3 Hit Judgment Logic

- Each target is divided into multiple scoring areas (e.g., center 10 points → outer ring 7 points → edge 5 points)

- Added "Perfect Hit" mechanism (small dot in the center of the bullseye + effect + bonus points)

- Bullet trajectory affects hit rate (based on shooting direction and charge intensity)
