🚀 The Challenge: Build a Full Game with Amazon Q CLI

As an indie developer who loves retro arcade games, I took on the Amazon Q CLI Game Dev Challenge to build something fast-paced, fun, and technically enriching — entirely powered by AI assistance.
The outcome was Emoji Rumble: a browser-based bullet hell survival game where players dodge waves of emoji enemies, use power-ups, and fight off boss monsters. It’s built with Flask, JavaScript Canvas, and a backend powered by MongoDB Atlas — all scaffolded and accelerated with Amazon Q CLI.

⚡ Amazon Q CLI: The AI That Coded with Me

Amazon Q CLI played a critical role — not just as a prompt-based assistant, but as a real coding partner.

Example Prompts I Used:

  • “Create a Flask backend with endpoints for leaderboard data.”
  • “Write JavaScript to control a player on HTML5 Canvas, dodging emoji enemies.”
  • “Add wave-based enemy spawn logic with scaling difficulty.”
  • “Implement 8-direction projectile power-up with cooldown.”
  • “Build leaderboard with score submission and top 10 retrieval.”
It accelerated prototyping, caught bugs, and even suggested performance improvements.

🕹️ Gameplay Summary

  • ▶️ Controls: Arrow keys (desktop), swipe input (mobile)
  • ⚔️ Waves: Enemy patterns increase in speed and complexity
  • 😈 Boss Fights: Triggered every 5 waves with special attack logic
  • 🧪 Power-Ups: Health, shield, slow-motion, bombs, freeze, and magnet
  • 📊 Leaderboard: Final score auto-submitted to MongoDB backend

🔍 Standout Features

  • Retro CRT-style visual filter
  • Dynamic, timer-based wave system
  • Emoji-based enemy AI
  • Power-up drops & pickup animations
  • Flask API + MongoDB for persistent score tracking

🧰 Stack Breakdown

HTML5 + JavaScript (Canvas) + Python + Flask + MongoDB Atlas + Render.com + Cloudinary (Audio)

🧠 Takeaway

Amazon Q CLI didn’t just speed up development — it reshaped how I think about solo building. I was able to go from scratch to full game logic, assets, and backend in days.
If you're building anything from CRUD apps to full games, I highly recommend giving Q CLI a try. It’s like pairing with an experienced engineer who never sleeps.
