It explains the important core points of C# well. It is helpful that it explains well where and why this C# grammar is used in relation to the game in the middle of the lecture. If you are completely new to programming, I recommend that you follow along step by step and understand it by looking at it several times. If you have experience using a slightly different programming language (such as Javascript, C++, or Java), you can quickly look over it and go over important or incomprehensible parts a few times. If you have tried C# before and your memory is vague, quickly looking over it will help you learn the newly added C# grammar and organize the forgotten C# content. And this is a side note, you will feel the force of an expert in the typing speed of the teacher of this lecture.
