Unable to change Time.timeScale

I’ve been scouring the internet trying to find if this issue has been resolved before, but to no avail.

I was trying to make a pause menu, which seemed simple enough. However, nomatter what I change Time.timeScale to it instantly reverts it back to 1…
after a while I tried manually changing it under Edit → Project Settings → Time, but it automatically reverts it back to 1 there too…

using UnityEngine;
using System.Collections;

public class PauseMenu : MonoBehaviour {

    bool paused = false;

    void Update ()
    {
        if ( Input.GetKeyDown( KeyCode.Escape ) )
        {
            Pause();
        }
   
        Debug.Log ( Time.timeScale );
    }

    void Pause()
    {
        paused = !paused;
   
        Time.timeScale = 1.0f - Time.timescale;
    }

    void OnGUI()
    {
        if ( paused )
        {
            var rect = new Rect( 10, 10, 100, 30 );
            rect.center = new Vector2( Screen.width/2, Screen.height/2 - 35 );
       
            if ( GUI.Button( rect, "Return to Game" ) )
            {
                Pause();
            }
       
            rect.center = new Vector2( rect.center.x, rect.center.y + 35 );
       
            if ( GUI.Button( rect, "Quit to Main Menu" ) )
            {
                // unpause / reset timescale before loading new scene
                Pause();
                Application.LoadLevel( "MainMenu" );
            }
        }
    }
}

Edit:
I realized there was a Questions specific area for stuff and made a post there, but can’t figure out how to delete this thread…

Look at the capitalisation on line 22. You will see one side is wrong. The colour coding of the text helps you find things like that.
