Vibe 2D Platformer

This project was implemented in order to submit to "Build Games Challenge: Build Classics with Amazon Q Developer CLI"

Challenge: https://community.aws/content/2y6egGcPAGQs8EwtQUM9KAONojz/build-games-challenge-build-classics-with-amazon-q-developer-cli

Repository: https://github.com/KovacZan/Vibe-2D-Platformer

Video: https://youtu.be/-vNyE4CPmxQ

The reason to participate in the challenge is to compare Q Developer CLI to Gemini CLI, which I started using recently.

Prompting

The game was implemented with two main prompts. I was experimenting with these prompts of various different retro games, but decided to go with a 2d platformer, since I have also implemented a 2d platformer game with Unity in the past.

1. Initial Prompt - REQUIREMENTS.md

Implement the REQUIREMENTS.md file for a 2D platformer game in Python.
The game should use the Pygame library for implementation.
The game should have a requirements.txt file for dependencies.
The game should use a virtual environment (venv) for its environment.
The game will later be implemented from the REQUIREMENTS using a prompt.

After getting the results, I am able to modify the requirements before getting into the implementation phase. That way I have a clear sight on what and how it will be generated.

2. Implementation Prompt

Implement a game based on the REQUIREMENTS.md file.

After this, I can add complementary prompts to fix bugs or change the game, but all things considered, with these two prompts, you can get a working, runnable product most of the time.

Conclusion

Compared to Gemini CLI as of the time of this writing, it looks like you can modify Amazon Q Developer CLI more than you can Gemini CLI.
I was amazed that Q Developer CLI implemented tests and executed them; if the tests failed, it went into a loop and fixed the game until it ran successfully.
It was a fun experience implementing a retro game so simply, without even writing any code myself, and just running the application that I wanted.
