Why I Built This Game
As part of the Amazon Q CLI Game Challenge, I decided to build a simple but fun Snake Game using Python and Pygame.
The goal was to explore how Amazon Q (AI assistant from AWS) can support game development and help us learn coding with ease.
I chose Snake because it’s a classic game that is both nostalgic and a great starting point for understanding game loops, input handling, and collision logic.
What I Learned
During this challenge, I learned:
How to use Amazon Q to generate Python game code using prompts
How Pygame handles game rendering, movement, and user input
The importance of breaking a project into smaller pieces (game loop, food generation, collision detection)
How to run Python code using virtual environments and install external libraries like Pygame
Even though I had some installation issues with Q CLI, I was able to use the web version of Q to get the code and build this game successfully!

Thank you AWS and Amazon Q for this fun opportunity. I enjoyed the challenge and learned how AI can help build creative projects.
I'm excited to keep exploring what else I can build with Amazon Q CLI!
