Recently, I have been busy with various things, so I came here after a long time, and I took the snake document clone lecture that you previously announced right away. I listened to it with interest while comparing it to the clone version that I had personally created. I took the lecture to learn how to teach, not how to develop, but this lecture was also great. ---- To those who are checking this review before taking the course. As written in the Q&A on the relevant page, you need to learn Part 3: Unity Engine first. Those who have some understanding of C# or Unity can proceed with the lecture without much difficulty, but since it relies on the framework created in Part 3: Unity Engine lecture, you may encounter work in a way that you have never seen before. For juniors who are planning to take this lecture for portfolio or skill improvement, I personally recommend that you study Part 3: Unity Engine lecture several times, and then gain an understanding of the core of the framework created during the lecture, and then take this lecture or the real game code review series.
