I thought a lot about it and bought it, but it was the perfect lecture for me. First, I watched a few videos and then I found it easier to view it in PDF format, so I was able to progress quickly and clear all three in two days. My study plan is to quickly follow along for the first time and understand the overall flow. (Complete) 2nd time - Take a close look at why it was written this way 3rd time - Try adding features to make the game more complete 4th time - Try refactoring using interfaces, delegates, etc. according to the contents of the book on dependency injection that I am reading separately 5th time - Complete the game without looking at any materials. The best thing about this lecture is that it provides PDF materials and that it covers only the necessary things concisely. After I finish this, I plan to watch parts 1 and 2, but I hope part 4 comes out.
