How Does Vibe Coding Work for Games?
Vibe coding means describing what you want instead of coding how to build it. For games, this transforms development from writing syntax to directing creativity. This article explains the principles introduced in our vibe coding overview.
The Basic Process
Step 1: Describe Your Vision
"Create a space shooter where planets have gravity"
Step 2: AI Generates Code
// AI writes: class Planet { applyGravity(ship) { const distance = this.position.distanceTo(ship.position); const force = (G * this.mass) / (distance * distance); ship.velocity.add(this.position.clone().sub(ship.position).normalize().multiplyScalar(force)); } }
Step 3: Test and Iterate
"Make gravity stronger near black holes"
The AI understands context and modifies accordingly.
What Makes Games Perfect for Vibe Coding?
Visual Feedback: You immediately see if the code works. A jumping character either jumps or doesn't.
Forgiving Errors: A bug might make gameplay interesting, not crash production systems.
Creative Freedom: "Wrong" behavior might be more fun than "correct" physics.
Isolated Systems: Games run client-side. No database corruptions or security breaches.
The Technical Stack
Modern vibe coding for games uses:
- Large Language Models: Understand natural language intent
- Code Generation Models: Convert intent to executable code
- Asset Generation: Create sprites, sounds, models from descriptions
- Runtime Environments: Execute generated code safely
At Rosebud, this stack runs entirely in browsers:
- LLM interprets your description
- Code generates in JavaScript
- Three.js renders immediately
- You play instantly
Common Vibe Coding Patterns
Adding Features
"Add double jump ability" → AI adds jump counter, resets on ground contact
Tweaking Gameplay
"Make enemies smarter" → AI implements pathfinding, predictive targeting
Visual Changes
"Make it look more cyberpunk" → AI adjusts colors, adds neon effects, changes assets
Fixing Issues
"The player gets stuck in walls" → AI adds collision detection, implements push-back
How AI Understands Game Context
The AI maintains understanding of:
- Game State: Player position, score, active enemies
- Code Structure: Classes, functions, variables
- Visual Style: Colors, themes, asset types
- Gameplay Loop: Win conditions, fail states, progression
This context allows natural conversations:
You: "Make it harder" AI understands: Increase enemy speed, reduce power-up frequency, add obstacles
The Iteration Speed Advantage
Traditional Development
- Write code (10 minutes)
- Compile (2 minutes)
- Test (5 minutes)
- Debug (20 minutes)
- Repeat
Vibe Coding
- Describe change (10 seconds)
- See result (instant)
- Refine (10 seconds)
The 100x speed improvement isn't hyperbole.
What You Can Build
Simple Games (Minutes):
- Flappy Bird clones
- Match-3 puzzles
- Basic platformers
Complex Games (Hours):
- Multiplayer battles
- RPG systems
- Physics puzzlers
Ambitious Projects (Days):
- Open world exploration
- Strategy games
- Social experiences
Complexity scales with imagination, not technical skill. Explore our approach to CLI agents for more advanced workflows.
Common Misconceptions
"It only makes simple games": Rosebud creators have built MMOs, complex RPGs, and physics simulations.
"The code is messy": Modern AI writes cleaner code than many humans, with consistent formatting and logical structure.
"You can't customize deeply": You can still edit generated code directly. Vibe coding accelerates, not restricts.
"It requires powerful hardware": Everything runs in browsers. If you can browse YouTube, you can vibe code.
Best Practices
- Start Simple: "Make a game where you collect coins"
- Iterate Incrementally: "Add enemies" then "Make enemies patrol"
- Be Specific When Needed: "Make jump height exactly 100 pixels"
- Use References: "Like Pac-Man but in 3D"
- Test Frequently: Play your game every few changes
The Learning Curve
Day 1: Creating basic games
Week 1: Understanding how to direct AI effectively
Month 1: Building complex systems through description
Month 3: Faster than traditional development for most projects
The skill ceiling isn't coding - it's creativity and game design sense.
Real Success Stories
- Developers shipping complete games in days using AI
- Non-programmers creating their first games in under an hour
- Rosebud creators: 1 million games and counting
These aren't exceptions. They're the new normal.
Getting Started

No downloads. No setup. No coding knowledge required.
The Future of Vibe Coding
As models improve:
- Better understanding of complex descriptions
- More sophisticated generated mechanics
- Smarter asset creation
- Eventually: describe entire worlds, get complete games
The tool evolves. Your creativity remains the constant.
