This course focuses on building a custom game framework and practical coding techniques for future maintenance, rather than on the implementation of the game itself. Therefore, it may be very difficult if you do not have prior knowledge of C# and Unity, as well as basic implementation skills. The pace of the course is also very fast, with the feeling that 10 minutes of this course contains about 1 hour's worth of content from other courses. However, if you can keep up with the course content and make it your own, I think you will gain a lot from this course.
