Console game isn't working.

Hey, i was editing my console game just to train my Csharp And i have a problem, one time after i was editing a script i saved and exited and the next day i went on and nothing was showing up on the console. i hope you can help, thanks.

Scrip CSharp:

using UnityEngine; using System.Collections;

public class NumberWizard : MonoBehaviour {

 // Use this for initialization
 int max;
 int min;
 int guess;
 
 void Start () {
     StartGame();
 }
 
 void StartGame () {
     max = 1000;
     min = 1;
     guess = 500;
     
     
     
     print ("========================");
     print ("Welcome To Number Wizard");
     print ("Pick a number in your head, But don't tell me!");
     
     print ("The highest number you can pick is " + max);
     print ("The lowest number you can pick is " + min);
     
     print ("Is the number lower or higher then " + guess);
     print ("Up = higher, Down = Lower Return = equal");
     
     max = max + 1;
 }
 
 
 void NextGuess() {    
     guess = (max + min) / 2;
     print ("Higher or lower then " + guess);
     print ("Up = higher, Down = Lower, Return = equal");
 }
 
 
 // Update is called once per frame
 void Update () {
     if (Input.GetKeyDown (KeyCode.UpArrow)) {
         min = guess;
         NextGuess();
     } else if (Input.GetKeyDown (KeyCode.DownArrow)) {
         
         max = guess;
         guess = (max + min) / 2;
         print ("Higher or lower then " + guess);
         
     }else if (Input.GetKeyDown (KeyCode.Return)) {
     
         print("I won!!");
         
         print("Want to play again? Press space");
         
     }else if (Input.GetKeyDown (KeyCode.Space)) {
     
         StartGame();
         
     }
 
 }

}
