This is a review written after studying up to Lyra's Input framework. Pros: Personally, I have learned a lot, and I feel I will grow even more through the remaining lectures. There are no other lecture videos that explain Lyra's framework by going through it **in order** like this one, so it is definitely a valuable course. Since it proceeds in a clone-coding format, it was easy to understand. Cons: 1. It has a strong "live broadcast" feel. I felt some disappointment regarding the preparation of the lectures. During the process, explanations are given while drawing on MS Paint, but it wasn't intuitive and felt quite abstract, so it didn't really resonate with me. It would have been better if materials were prepared separately instead of using MS Paint. Personally, this part made me feel like I wasn't getting my money's worth. 2. It felt more like the instructor was reciting their own understanding rather than providing explanations tailored for the listener's comprehension. I particularly struggled during the camera chapter. However, for those with intermediate Unreal Engine skills, it is a course that can be fully managed through review. Final Thoughts: If you are an Unreal Engine beginner, I strongly recommend taking other basic Unreal Engine courses instead of this one. I don't mean you shouldn't take this course at all. It's just that for beginners, the efficiency relative to the time invested might not be high, so it would be better to take this after strengthening your foundations. Personally, I have intermediate-level skills, and I am finding it very informative. Although I frequently feel that the lecture preparation and teaching quality are lacking for the price, the value of the lecture topic itself is so high that I am studying hard. It seems that the personal framework I've applied while developing games will be greatly improved thanks to this course.
