[Hardcore Challenge Season 3] 5-Week Track: Entering Indie Development with Your Own RPG Game

Welcome to the Intensive Challenge..

This course is a small, elite challenge designed to help even complete beginners take their first steps toward becoming an indie game developer. This challenge is conducted in a small group to provide personalized 1-on-1 mentoring.

You will experience everything from C# basics to creating a 2D RPG game and directly publishing it to itch.io after a WebGL build. We systematically cover the essential theory and practice required for the game development process.

In fact, while it has become easier to learn game development these days, for those starting for the first time, finding direction—knowing what to learn first and how to approach it—is the most important thing. Based on my experience teaching numerous students over the past 15 years, from Fast Campus offline lectures to serving as an online tutor at Team Sparta, I have prepared this Intensive Challenge.

Intense Challenge Goals

• Clearly present the amount of work to be completed each week and check progress.

• C# Beginner/Intermediate/Advanced Syntax & Transitioning to Game Development Thinking

• From Unity Editor basics to Sprite, Tilemap, and UI creation

• Implement RPG character movement, animation, and combat systems using appropriate design patterns

• Sound, story, UI, local and cloud save features

• Finally, directly distribute to itch.io and complete a playable build

The direction for growing into a game developer equipped with AI utilization skillsnăng lực ứng dụng AI

As the competencies required of game developers in the AI era are rapidly changing, I have put a lot of thought into which direction this challenge should
take.

Various AI development tools, including ChatGPT, Claude, and Copilot, are emerging and evolving every day. In this environment, a more important question than "which AI to use" is as follows:

How can AI be utilized to maximize one's fundamental skills and capabilities as a game developer?

AI immediately generates high-quality code. However,

"Vibe coding," which relies solely on code provided by AI, is bound to fail in the end.

The Role Required for Developers in the AI Era: A Supervisor, Not an Implementer

To perform this role, the following two things are absolutely essential.

In other words, the ability to utilize AI effectively is only meaningful when you have a solid foundation. Therefore, the first goal of this challenge is:

"Securing your own foundational capabilities before relying on AI"

Only when you have the fundamentals can you understand the intent behind AI-generated code, modify and optimize it as needed, and expand it to align with the game's direction.

Intensive Challenge How is AI utilized?

In this challenge, you will not simply learn "how to ask AI for code." Instead, you will utilize AI in the following ways.

• Code validation using Claude Code

  
  

• SOLID principles and Clean Code standards-based inspection

• Learning methodologies to continuously improve code quality

In other words, instead of having AI write the code for you, you will learn how to improve your own code through AI. A Claude Pro plan ($20/month subscription) is required.

Intensive Challenge Curriculum Introduction

[Week 0: Utilizing Git & GitHub]

Before diving into the full-scale challenge, you will first learn how to use Git and GitHub, which are essential for any developer. (Optional)

Through the pre-provided Git/GitHub lecture, you will understand version control concepts and manage all code used during the challenge directly with Git. Additionally, you will practice how to share and structure code through GitHub.

This challenge is about more than just writing code.

Growing into a collaborative developer through the experience of managing, recording, and sharing code is one of the important goals. We hope that all participants will become proficient in using Git through this process and further grow into developers capable of collaboration. (Free coupon provided)

[Weeks 1 & 2: Building Solid C# Programming Skills]

The core of this challenge is to build solid C# programming fundamentals.

Many introductory courses get stuck in tedious grammar explanations, but this course is different. You will naturally master C# syntax and learn advanced techniques while building your own text-based RPG game.

• From basic C# syntax such as variables, conditional statements, and loops to

  
  

• Class, inheritance, encapsulation, polymorphism, and other Object-Oriented Programming (OOP) concepts

  
  

• And even SOLID principles and clean code writing techniques

  
  

You will learn step-by-step in connection with actual game production. This learning method is a structure designed to go beyond simply understanding concepts and ensure they are naturally repeated and connected when implementing a 2D RPG with Unity.

In other words, the learning process itself is connected to the Unity game development process, structured to maintain a natural flow.

[Week 3: Unity Basics and 2D RPG Project Design]

In Week 2, we will learn the basics of using the Unity engine and proceed with the design phase for creating an actual 2D RPG game.

Creating a game design document is an essential process regardless of the genre or scale of the game. We have structured this course to help you develop the ability to design and structure games on your own using provided templates. Once the design is complete, we will begin the full-scale game production.

Key Learning Content

[Week 4: Combat, Inventory, and Save Functions]

In Week 3, we will begin implementing the combat system and inventory features, which are the core of an RPG game.
Although it involves somewhat complex logic, the course is structured to help you understand naturally by practicing step-by-step approaches and efficient structural design methods.

Key Learning Content

[Week 5: Build, Deployment, and Portfolio Creation]

In Week 4, we will polish (the process of refining to a publishing quality level) the project created so far and then proceed with optimization for WebGL building.

Furthermore, beyond simply completing the game, we will proceed with uploading to GitHub, writing README documentation, and itch.io distribution to enhance its value as a portfolio.nâng cao giá trị cho hồ sơ năng lực (portfolio) của bạn.

Participants who deploy their projects to itch.io within the specified period will receive a full project review and improvement feedback.

Key Learning Content

[Total of 4 Live Special Lectures and 1:1 Individual Mentoring]

Weekly special lectures are held every Tuesday evening from 20:00 to 22:00 (2 hours). A total of 4 lectures will focus on content not covered in the challenge curriculum or areas that need reinforcement through live instruction.
(Optional participation, day and time, and lecture topics are subject to change.)

• The special lecture topics will be finalized on the challenge opening day.

• A recording will be provided so that you can review the material after the special lecture is completed.

• Individual 1-on-1 video mentoring sessions are held once a week (30 minutes). This is limited to applicants, and the schedule will be announced on the Slack channel.

• Individual mentoring is limited to content related to the curriculum.

  
  

Intensive Challenge Process

• Assigning weekly missions and sharing progress

• Progress verification (required) and a total of 4 one-on-one Zoom video mentoring sessions (optional)

• Code sharing and code reviews on GitHub

• Sharing the Slack channel with students

• Q&A via Slack and Inflearn

• Project review provided after uploading the final portfolio

• Upon completion of the final mission, discount coupons for all courses I have opened will be provided

  
  

Recommended for the following people.

• Those who are determined and aim to complete game development within 5 weeks.

• Someone whose dream is to be an indie game developer

• Job seekers who need a portfolio

• Those who are starting game development for the first time

  
  

• Those who need a practice-oriented course rather than theory.
