Oh, I suddenly thought this was a lecture for beginners, but it's really really good.. It's ridiculous that they give out source codes to the point where I wonder if they can make this content come alive like this. I like it because it feels like my code, which has become rigid as an indie, can be modified. I wish they had explained the structure a little more, but then I don't know if I should take the Unity lecture. Anyway, thank you~~
