Building Space Explorer with Amazon Q CLI: A Weekend Game Development Journey

How I went from zero to a fully-featured space shooter game using AI-powered development


The Challenge: Build a Game with Just Prompts

When I heard about the "Build Games with Amazon Q CLI" campaign, I was intrigued by the promise of creating games through natural language conversations with an AI. As someone who's always been fascinated by game development but often got bogged down in the technical details, this seemed like the perfect opportunity to focus on creativity and game design rather than wrestling with syntax errors.

My goal was ambitious: build a complete space shooter game over a weekend using nothing but prompts to Amazon Q CLI. The result? Space Explorer - a feature-rich game that exceeded my wildest expectations.

Day 1: From Concept to Core Mechanics

Starting Simple: "Build me a basic space shooter"

My first prompt was refreshingly straightforward: "Help me create a Python space shooter game using Pygame with a player ship that can move and shoot."

Within minutes, Amazon Q CLI had generated a working foundation with:

  • A player-controlled spaceship

  • Basic movement mechanics

  • Simple bullet firing system

  • Enemy spawning

What struck me immediately was how the AI didn't just give me code - it provided well-structured, readable code with proper class organization. The foundation was solid enough to build upon, which is often the hardest part of any project.

Iterating with Natural Language

The real magic happened when I started refining the game through conversation:

"Add different types of enemies - some basic ones that shoot straight down, and smart ones that aim at the player"

"Create a power-up system with health, shields, and weapon upgrades"

"Add particle effects for explosions and visual feedback"

Each request was implemented not just functionally, but thoughtfully. The AI understood the context of a space shooter and made design decisions that made sense - smart enemies had health bars, particle effects had appropriate colors and lifespans, power-ups had visual indicators of their type.

Day 2: Advanced Features and Polish

The Boss Battle Breakthrough

One of my favorite moments was when I asked: "Add a boss enemy that appears every 10 kills with multiple attack phases"

Amazon Q CLI created a boss system that was more sophisticated than I had imagined:

  • Phase 1: Simple direct shots

  • Phase 2: 360-degree bullet patterns

  • Phase 3: Aimed projectiles with spread patterns

The boss even moved dynamically across the screen and had a substantial health bar. This wasn't just functional code - it was engaging game design.

The Small Details That Matter

What impressed me most was how Amazon Q CLI handled the polish requests:

"Add a starfield background that scrolls" "Create a persistent high score system" "Add visual feedback for shield activation"

Each of these requests resulted in thoughtful implementations. The starfield used a mathematical pattern for smooth scrolling, the high score system used JSON for persistence, and the shield had a subtle cyan outline that pulsed when active.

The Technical Marvel Behind the Scenes

Code Quality That Surprised Me

The final codebase was remarkably well-organized:

pythonclass Player:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.speed = 5
        self.health = 100
        # ... clean, readable initialization

    def update(self):
        # Logical separation of concerns
        self.handle_input()
        self.update_position()
        self.update_cooldowns()

The AI consistently applied good programming practices:

  • Single Responsibility Principle: Each class had a clear purpose

  • DRY Code: Repeated logic was abstracted into methods

  • Error Handling: File operations were wrapped in try-catch blocks

  • Performance Awareness: Efficient collision detection and memory management

Advanced Game Programming Concepts

Amazon Q CLI seamlessly implemented complex game development patterns:

Component-Based Architecture: Each game entity (Player, Enemy, Boss, Bullet) was a self-contained component with update/draw methods.

State Management: The game handled multiple states (playing, game over, boss fights) cleanly.

Physics and Collision: Implemented proper circular collision detection with visual feedback.

Particle Systems: Created dynamic explosion effects with proper lifetime management.

The Creative Process: AI as a Collaborative Partner

Beyond Code Generation

What surprised me most was how Amazon Q CLI functioned as a creative partner rather than just a code generator. When I asked for "more interesting enemy behaviors," it suggested:

  • Enemies that predict player movement

  • Formation flying patterns

  • Different enemy archetypes with unique abilities

Problem-Solving in Real-Time

When I encountered issues, the AI was exceptional at debugging:

"The collision detection feels off, enemies seem to hit from too far away"

The response wasn't just a code fix - it was an explanation of collision detection principles and multiple approaches to solve the problem, from bounding boxes to distance-based detection.

Balancing Suggestions

Amazon Q CLI even helped with game balance:

"The game feels too easy/hard"

This led to discussions about:

  • Dynamic difficulty scaling

  • Power progression curves

  • Enemy spawn rates

  • Health/damage ratios

The Final Product: Space Explorer

After two days of iterative development, Space Explorer featured:
