Real-time gameplay with Colyseus

What are you most proud of, and what would you do differently next time?

To make the project more interesting, I've added a few extra features:

• Single-player mode with Bot: Implemented using the Minimax algorithm
• Multiplayer mode: Real-time competition powered by Colyseus.

What challenges did you encounter, and how did you overcome them?

Challenges encountered with AI:

• Complex Logic & Edge Cases: When the logic became complex (e.g., handling user disconnections, redesigning server state, providing proper UI hints, or managing async side effects on the frontend), the AI didn't do so well. I found it necessary to think through the edge cases myself and decide on the best user experience.

• Outdated Packages: While setting up Colyseus, the AI fell into an infinite loop trying to use the deprecated colyseus.js package. Instead, I used npm create colyseus-app@latest ./server based on the official documentation, and manually edited the files step-by-step before integrating with the Angular client.

• Testing Constraints: Writing E2E or Unit tests with AI still requires careful review. Although AI writes code quickly, it doesn't always reflect a true double-check for edge cases or real user expectations. Relying on official documentation is still the best practice here.
