I changed a little bit a greeting from the lecture 
Debug.Log("Hello! Welcome to Number Wizard, the best game you ever played!");
Debug.Log("Pick a number, don't tell me what it is my comrade!");
Debug.Log("The highest number you can pick is: " + max);
Debug.Log("The lowest number you can pick is: " + min);
Debug.Log("Tell me if your number is higher or lower than: " + guess);
Debug.Log("Push Up = Higher, Push Down = Lower, Push Enter = Correct");
max = max + 1;
