  weather: { current, intensity },
  time: { gameTime, day }
}
```

## 🛠️ QUICK ENHANCEMENTS

### Add Auto-Save:

In GameScene.update():
```javascript
// Auto-save every 5 minutes
if (!this.lastSaveTime) this.lastSaveTime = Date.now();

if (Date.now() - this.lastSaveTime > 300000) {
    if (this.saveSystem) {
        this.saveSystem.saveGame();
        this.lastSaveTime = Date.now();
        console.log('💾 Auto-save complete');
    }
}
```

### Add Multiple Slots:

Modify SaveSystem:
```javascript
saveToSlot(slot) {
    const key = `novafarma_save_${slot}`;
    // ... save logic ...
    localStorage.setItem(key, JSON.stringify(saveData));
}

loadFromSlot(slot) {
    const key = `novafarma_save_${slot}`;
    const data = localStorage.getItem(key);
    // ... load logic ...
}
```

## 🎮 CURRENT USAGE

**Save Game:**
```javascript
// F5 key (already set up)
gameScene.saveSystem.saveGame();
```

**Load Game:**
```javascript
// F9 key (already set up)
gameScene.saveSystem.loadGame();
```

## 💡 RECOMMENDATION

**Keep existing system for now!**

Why:
1. ✅ Already works
2. ✅ Already integrated
3. ✅ F5/F9 keys functional
4. ⏳ Can enhance later

**Focus on:**
- Testing current save/load
- Verify all systems save correctly
- Add auto-save (5 min interval)
- Polish Phase 4 & 5 instead
