Launch a Mobile Game with Vibe Coding from the App Store’s #1 Puzzle Game Developer: GPT·Codex in Practice
It doesn’t stop at following along to create a sample game.
Using ChatGPT- and Codex-based vibe coding, you’ll learn the entire process through a real launch project: from game planning → development → mobile builds → AdMob ad integration → publishing on ONE store, Google Play, and the App Store.
This course is related to monetization/side business. Results may vary by individual, so please consider your purchase carefully.

이런 경험, 있으시죠?
Anyone can make an AI game, but launching one is another story.
Most people get stuck at the following three points. This course was created specifically to help you get past them.
1
Those who get stuck at “What should I make?”
Many people get stuck nurturing an idea without ever getting started. This course teaches you how to start imperfectly.
2
Those who failed because their code became tangled
Have you ever had the experience of making things more tangled the more you tried to fix them? We’ll show you how to roll back using workflow rule files and GitHub safeguards.
3
Those who gave up during review/integration
Many people give up during store review, builds, and ad integration. This course walks you through the registration process for three stores.

말보다 결과로 보여드립니다.
A game created with vibe coding reached No. 1 on the App Store charts.
The game Rune Raid, which I personally released through vibe coding, topped the App Store paid game download chart, surpassing titles like Monopoly, Rummikub, and Wingspan. I didn’t write the code myself.

The game created in the course has been released on the App Store (sold for ₩1,100)The same game has also been released simultaneously on ONE store and Google Play.
You can play the game made in the course yourself. Check out the five curriculum lectures with free previews.
지식공유자
I have been making games on my own for 10 years, and released six games in just one year.
Baek Ho-yeon · YouTube WebHack operator (13.1K subscribers) · 10th-year solo game developer
The game I created, “Step Cave,” has been selected as a nominee for the 2026 Excellent Game of the Year Award (indie game category).
10 years
I made a game by myself.
Released over 15 games on Google Play. I kept making games while switching between genres, including roguelikes, puzzles, tower defense, and deck-building.
In the meantime
I made 5 million won a month, but I also ended up failing.
“Made 5 million won a month through solo game development, then went under” (140K views), “What I felt while releasing games with vibe coding” (240K views) I documented my successes and failures exactly as they happened on YouTube.
Turning Point
After discovering vibe coding, “it felt like I had gained an employee.”
I started using the time I used to spend writing code for planning and preparing for releases. As a result, I released six games over the course of a year.
Recognition
Selected as a finalist for the 2026 Outstanding Game of the Year!
The solo-developed game ‘Step Cave’ has been nominated. This is a developer who has created games that keep selling—not just a hobby project.
Results
App Store paid game downloads ranked #1!
A game created without writing the code directly reached #1 on the charts. I continue to repeat the process of launching and monetizing games, including Rune Raid, which has a 4.8 rating.
Now
That entire process is covered in 78 lessons without leaving anything out.
The key is knowing how to make requests to AI. I’ve reorganized 10 years of trial and error from a non-specialist’s perspective.
I personally answer questions left in the course reviews, and I re-record and re-upload any lessons that are lacking. (Windows environment supplementary update completed on 2026.06.23)
커리큘럼 · 전체 78강 11시간 30분
From planning to release, the process proceeds in four stages.
I’ll walk you through the process of completing a game and publishing it to the store, step by step.
STEP
1
Reality Check and a Safe Work Environment (Sections 1–3 · 10 Lessons)
We’ll explain why games can’t be created with a single “click,” why we use Phaser instead of Unity, and how to set up GPT, Codex, VS Code, and GitHub.
Set up a web development environment where changes are immediately visible, along with GitHub safeguards that let you roll back at any time.
STEP
2
Creating Rules to Treat AI Like an Employee (Sections 4–5 · Lesson 5)
Write agents.md, design.md, and codex.md yourself to establish the rules for AI's work. Then, learn how to create a prototype in just one day.
This is the most useful section. After taking this course, try copying it directly into your own project and using it.
STEP
3
Actually Completing the Game (Sections 6–8 · 52 Lessons)
From core gameplay through repeatable content → structural redesign → graphics, UI, and sound effects → polishing, we show you the entire process of improving the game through conversations with AI.
STEP
4
With Smartphones, and Through the Stores (Sections 9–10 · Lesson 11)
From mobile builds to AdMob ads → in-app purchases → release on ONE store, Google Play, and the App Store → post-launch updates! We’ll introduce the process of launching and generating revenue. Follow along with the review and registration screens step by step.
The lecture slide PDF, complete game source code, and the full prompts actually used are provided.
누가 들어야 할까요
We’ll be honest about who this course is right for.
This is definitely for people who:
Those who want to create and sell their own game without coding experience
Those who started making it with AI but got stuck at the completion and release stage
Those who want to complete a mobile build, AdMob integration, and store registration from start to finish at least once
Those who want to build a revenue stream through solo development or a side business
Not recommended for those who:
Those who want to learn 3D large-scale game development based on Unity or Unreal Engine
Those expecting a game to be completed with a single click.
Those who want to learn code structure and algorithms theoretically

Reviews from Those Who Listened First
“I liked how you explained the process of creating a game with AI step by step in a way that even beginners could easily understand. The videos were a manageable length, making it easy to stay focused, and I found it reassuring that they naturally incorporated your practical know-how from reaching number one on the App Store.”

Frequently Asked Questions
I’ve never coded before. Is it possible for me?
It’s possible. This is a beginner-level course, and you won’t write code yourself. We’ll install and set up the necessary tools (Codex, VS Code, GitHub, etc.) together as part of the course.
Are there any additional costs?
A ChatGPT subscription is required to follow along with the hands-on exercises. If you actually publish to the stores, developer registration fees apply: $25 one-time for Google Play and $99 per year for the App Store. You can also simply learn without publishing.
Is it possible on Windows as well?
Development and publishing to Google Play and ONE store are possible on Windows. To carry out the App Store publishing process yourself, you need macOS. The instructions for Windows users were expanded in the 2026.06.23 update.
Why Phaser instead of Unity?
Because changes are immediately visible on screen in a web environment, it is the fastest way to collaborate with AI. The reasons are covered in detail in Section 3.
Can I ask questions if I get stuck?
Yes. You can ask questions about the course content and issues that arise while working on your project through the course-exclusive one-on-one KakaoTalk chat.
Next week, you’ll be able to say, “My game is out.” Get started with WebHack!

I loved how you explained the process of making games with AI step-by-step, making it easy for even beginners to understand! The video length was just right, so it was easy to stay focused, and since it naturally included practical know-how from someone who has reached #1 on the App Store, it felt very trustworthy. I'll keep following along diligently until the end! 👍
Hello, Murim Park.
I should have paid more attention to the students' development environments, and I apologize for the inconvenience caused.
I have re-uploaded the two videos you mentioned with sufficient additional explanations so that they can be completed on Windows without any issues.
If there are any other parts that are difficult to follow, please let me know. I will continue to provide updates!
