It was good that there was a part explaining the UI. I only had a taste of other game engines, not many, and I came to this lecture, but each game engine has different UIs and functions, so it was a bit difficult to start from scratch. It was easy to learn about the engine itself because the UI was explained. However, for those who have never been in contact with development, it seems that the variables and file names were in Korean, and the last letter was skipped, so it was a bit uncomfortable. I listened well.
