How to Create a Simple Game in 2 Hours Using AI Coding Tools

If you're an indie hacker or a solo founder, you know the feeling of wanting to create something fun but being overwhelmed by the complexities of game development. The good news? With the rise of AI coding tools, you can build a simple game in just two hours—even if you're a complete beginner. In this guide, I'll walk you through the process, share some essential tools, and offer real insights from our own experiences.

Prerequisites: What You Need to Get Started

Before diving in, here’s what you’ll need:

• A computer: Windows, Mac, or Linux will work.
• An internet connection: Most AI tools are cloud-based.
• Basic understanding of programming concepts: While you don’t need to be a pro, familiarity with variables and functions helps.

Step 1: Choose Your Game Concept

Start with a simple idea. A great beginner project is a text-based adventure game or a simple 2D platformer. For this tutorial, we’ll go with a text-based adventure game that can be easily expanded later.

Step 2: Select Your AI Coding Tool

Here’s a breakdown of some popular AI coding tools that can help you build your game quickly:

| Tool Name | What it Does | Pricing | Best For | Limitations | Our Take | |------------------|------------------------------------------------|------------------------------|----------------------------------|--------------------------------------|-------------------------| | OpenAI Codex | Generates code snippets based on prompts | $20/mo for pro plan | Text-based games | Limited context understanding | We use this for quick code generation. | | GitHub Copilot | Autocompletes code as you type | $10/mo, free for students | General coding assistance | Can miss complex logic | Great for getting unstuck. | | Replit | Online IDE with AI-assisted coding | Free tier + $7/mo pro | Collaborative coding | Performance can lag with heavy use | Perfect for real-time collaboration. | | Unity | Game engine with AI tools for rapid prototyping| Free for personal use, $25/mo for pro | 2D/3D game development | Steeper learning curve for beginners | Powerful but complex. | | ChatGPT | Conversational AI for brainstorming ideas | Free, $20/mo for Plus | Idea generation and code review | Limited to text-based interaction | Use it for brainstorming and debugging. | | GameMaker Studio | Drag-and-drop game creation tool | $39/one-time license | Beginners in 2D game development | Less flexibility for coding | Good for visual learners. | | Scratch | Visual programming language for games | Free | Kids and absolute beginners | Limited to simple games | Fun for prototyping ideas. | | Pygame | Framework for building games in Python | Free | Simple 2D games | Requires Python knowledge | We prefer it for quick prototypes. | | Construct 3 | Browser-based game development platform | Free tier + $16/mo pro | 2D games without coding | Limited customization options | Good for non-coders. | | Godot | Open-source game engine with scripting support | Free | Indie game development | Smaller community than Unity | Solid choice for flexible game design. |

Step 3: Outline Your Game Logic

Before you start coding, sketch out your game flow. For a text-based adventure, you might have:

1. Introduction: Set the scene and give the player options.
2. Choices: Different paths based on player decisions.
3. Endings: Multiple outcomes based on choices made.

Step 4: Start Coding

Here’s a simple structure you can use for your game, using OpenAI Codex or GitHub Copilot:

def start_game():
    print("Welcome to the Adventure!")
    choice = input("Do you want to go left or right? ")
    if choice == "left":
        print("You encounter a dragon!")
    elif choice == "right":
        print("You find a treasure chest!")
    else:
        print("Invalid choice. Try again.")
        start_game()

start_game()

Expected Output

When you run your game, you should see a prompt welcoming players and giving them a choice. Depending on their input, the game will respond accordingly.

Troubleshooting: What Could Go Wrong?

• Error messages: If you encounter syntax errors, check your code for typos.
• Game logic not working: Review your conditions and ensure they’re set up correctly.
• Tool limitations: If your AI tool struggles with a specific request, try rephrasing your prompt.

What’s Next: Expanding Your Game

Once you’ve built your basic game, consider adding:

• More choices: Create additional paths for players.
• Graphics: Use tools like Unity or Pygame to add visuals.
• Sound effects: Incorporate audio for a more immersive experience.

Conclusion: Start Here

Creating a simple game with AI coding tools is not only possible but also a fun way to learn coding. Start with a basic text adventure, use the tools listed here, and don’t hesitate to iterate on your ideas.

What We Actually Use

For quick prototyping, we typically rely on OpenAI Codex and GitHub Copilot for code generation and debugging. Replit is our go-to for collaborative work.
