This is what I was going to put, but I realized that the Debug.Log call has a limited number of arguments you can put in it. I’ll probably be revising it to make it work correctly.
Debug.Log("Howdy! I'm the number wizard.");
Debug.Log("Pick yourself a number between " +minGuess, " and ", +maxGuess, "but don't tell me what it is." );
Debug.Log("The highest number you can pick is: " +maxGuess);
Debug.Log("The lowest number you can pick is: " +minGuess);
Debug.Log("Tell me if your number is higher or lower than " +plrGuess);
Debug.Log("If I guessed too low, push UP. If I guessed too high, push DOWN. Push ENTER if I got it right.");
