Little issue with switching in between Main Menu and the other scene

The main menu I developed as a scene, consisting in an image and the "Start" text in the middle. To the "Start" text, I attached a script:

Code (CSharp):

1. public class Start_Script : MonoBehaviour {
2.  
3.     void OnMouseEnter()
4.     {
5.         Application.LoadLevel ("Game");
6.     }
7.  
8.     void Update()
9.     {
10.         if(Input.GetKey(KeyCode.Escape))
11.         {
12.             Application.Quit();
13.         }
14.     }
15. }

And in the main script, you have to remember this:

Code (CSharp):

1. void Update()
2.     {
3.         if (Input.GetKey (KeyCode.Escape))
4.         {
5.             Application.LoadLevel ("Main Menu");
6.         }
7.     }

Yes they are correctly named "Game" and "Main Menu". But, after building the game, when clicking the "Start" text, nothing happens. Any idea on how to solve this? Much appreciated, guys.

 

did you include all the scenes in the build?

 

Yes, I did. I only have 2 scenes. The "Main Menu" and "Game" ("Game" is just one scene).
