   - **Impact**: Potential challenges in maintaining consistency across environments and efficiently managing infrastructure resources.

9. **Lack of Clear Separation Between Game Logic and Backend Services**:
   - **Issue**: The game logic appears to be primarily handled by the frontend game engine, with backend services supporting features like multiplayer and leaderboards.
   - **Impact**: May lead to increased workload on client devices and potential security risks if critical game logic is exposed to the client.

### **1.2. Areas for Improvement**

1. **Adopt a Microservices Architecture**:
   - Break down backend functionalities into discrete, independently deployable services to enhance scalability and maintainability.

2. **Enhance Real-Time Communication Handling**:
   - Implement specialized services or protocols optimized for low-latency, real-time data synchronization to improve multiplayer experiences.

3. **Refine Database Strategy**:
   - Clearly delineate responsibilities between relational and NoSQL databases, possibly introducing separate databases for transactional and analytical data.

4. **Strengthen Security Measures**:
   - Incorporate game-specific security strategies, such as anti-cheat mechanisms, secure real-time data channels, and enhanced encryption standards.

5. **Integrate Data Analytics Components**:
   - Introduce dedicated services for collecting, processing, and analyzing player data to drive game improvements and personalized experiences.

6. **Improve Deployment and Infrastructure Management**:
   - Utilize Infrastructure as Code (IaC) tools, define clear environment configurations, and implement comprehensive monitoring and alerting systems.

7. **Optimize API Gateway Usage**:
   - Explore the use of multiple API gateways or API management solutions to distribute traffic and reduce latency.

8. **Separate Game Logic from Client-Side**:
   - Shift critical game logic to backend services to enhance security and reduce dependency on client devices.

9. **Enhance Modularity and Extensibility**:
   - Design components with clear interfaces and modularity to facilitate future enhancements, feature additions, and third-party integrations.
