### 🐛 KNOWN ISSUES & FIXES

**Fixed:**
1. ✅ CollectionSystem sound error (`playSuccess is not a function`)
2. ✅ NPC scale inconsistencies
3. ✅ Settings menu visibility
4. ✅ Language selector UI/UX

**Known Issues:**
1. ⚠️ NPC AI sprite transparency (checkerboard pattern) - Low priority
2. ⚠️ Steam integration requires Greenworks SDK for production

### 📋 NEXT STEPS

**Immediate (Ready to Implement):**
1. **Integration Testing** - Test all new systems together
2. **UI Polish** - Rustic/Post-apo theme for remaining UI
3. **Trailer Tools** - Smooth camera movement scripting
4. **Save/Load System** - Integrate with Steam cloud saves

**Future Features:**
1. **Seasonal Crops** - Extend perennial system to wheat/corn
2. **More Mounts** - Implement horse properly
3. **Achievement Triggers** - Wire up gameplay events to Steam achievements
4. **Volume Controls** - Implement sound settings UI

### 💡 DESIGN DECISIONS

1. **Localization Architecture:** Embedded translations vs external JSON files
   - Chose embedded for simplicity and instant loading
   - Can be externalized later if needed

2. **Mount System:** Inventory-based vs NPC-based
   - Chose NPC-based for better world interaction
   - Allows for mount status (health, stamina in future)

3. **Steam Integration:** Mock vs Direct SDK
   - Implemented mock system for development
   - Easy to swap to real Greenworks when publishing

4. **Main Menu:** Scrolling intro vs Static menu
   - Changed to static for better UX
   - Intro can be triggered separately (cutscene)
