Create new `WebInputHandler(InputHandler)` +2. Create new `WebRenderer(GameRenderer)` +3. Initialize in `Ophidian.__init__()` with `use_web_ui` flag +4. **No changes to GameEngine needed!** + +### 3. **Maintainability** +- Gameplay changes don't require UI updates +- UI changes don't risk breaking gameplay +- Each component can be tested independently +- Clear interfaces between components + +### 4. **Testability** +```python +# Test gameplay without any UI +engine = GameEngine(config) +engine.initialize_game() +engine.handle_direction_input(DirectionMapper.UP) +engine.update() +assert engine.level == 1 +``` + +### 5. **Code Reuse** +- Same `GameEngine` for all UIs +- Same input action definitions +- Shared game state structure + +## Backward Compatibility + +The refactored `Ophidian` class maintains backward compatibility through: + +1. **Property Delegates**: Old attributes delegate to `GameEngine` + ```python + @property + def level(self): + return self.game_engine.level + ``` + +2. **Existing Method Signatures**: Public methods maintain same signatures +3. **Gradual Migration**: Old code paths still work during transition + +## Future Enhancements + +With this architecture, these additions become trivial: + +1. **Network Multiplayer**: Add `NetworkInputHandler` +2. **AI Player**: Add `AIInputHandler` +3. **Replay System**: Record/playback `InputAction` sequences +4. **Mobile UI**: Add `TouchInputHandler` and `MobileRenderer` +5. **Web UI**: Add `WebSocketInputHandler` and `CanvasRenderer` +6. **Testing**: Mock `InputHandler` for automated gameplay testing + +## Example: Adding a New UI + +```python +# 1.
