Working as a game designer, there are often moments when you feel lost, not knowing how to plan sound or how to collaborate with the audio team. In particular, questions like "What makes good sound?", "Why does my game lack impact?", and "Why don't scene transitions/UI/combat/ambient sounds connect into a cohesive experience?" are among the most challenging areas for designers with limited experience. This course is designed for designers with these concerns, explaining the principles of sound design in a designer's language and helping you understand step-by-step, aligned with actual workflow, what role sound plays in games and how it should be designed. Focusing on core concepts and real-world examples that make up game sound— such as sound direction, impact feel, feedback, layering, ducking, and trigger design— this course explains things concretely and practically so that even beginner designers without audio expertise can easily understand and immediately apply them to their work. After taking this course, you won't be a designer who relies on vague intuition saying "just do it like this," but rather one who understands various game sound techniques and can proactively lead audio quality.

"We will finish the top 3 most used but most confusing concepts in practice (Generics, Lambdas, Streams) in just one hour."

This is an introductory course for beginner game designers who find quest design overwhelming. It helps you move beyond quests that don't go past the "kill X monsters" level, and explains step-by-step why players take action and how choices become experiences. Centered on real commercial game examples and the designer's thought process, it teaches you the fundamental design methods for connecting quests with story, gameplay, and systems.

It is structured so that non-majors, students, and the general public can easily become interested in programming through the programming language called C#. It is a beginner's course that can help you gain confidence in programming through easy expressions and follow-through.

It's an undeniable fact that mathematics is essential for game developers. Instead of excessively deep traditional math lectures, learn all the mathematical techniques you can use right away!

PCG (Procedural Content Generation) is a design approach that automatically generates game content based on rules and conditions. It is utilized for various content such as maps, items, events, and quests, and is currently widely used throughout the game industry to improve development efficiency and gameplay variety. PCG is no longer limited to specific genres or technical teams; it has become one of the fundamental concepts that game designers must understand. PCG is often misunderstood as merely a mathematical or programming technique, but in reality, the most important aspect is the planning-stage choices and design that determine "what kind of experience to create repeatedly." This course is an introductory lecture focused on understanding and utilizing PCG from a designer's perspective. Rather than teaching how to write code, it gradually explains why PCG is necessary, what problems it solves, and how it is used in game design, centered on principles and case studies.

This is an introductory VR development course that teaches you how to connect VR equipment and develop VR content using Unity.
