Lastly, we learned about simple procedural programming and how much cleaner code can be when repeated instructions are abstracted out into their methods.

You should feel a sense of accomplishment at this point, especially if you started this book as a total beginner. Getting up to speed with a new programming language while building a working game is no easy trick. In the next chapter, you'll be introduced to some intermediate topics in C#, including new type modifiers, method overloading...
