Unity Engine

I’m having a small Issues with playerprefs i’ve got it so it saves the Score of my game and loads it

but i’m trying to get to to accumulate scores for an unlock level system any help with this would be great thanks

and yes i know the code doesn’t look good at the moments but its still working process

MainMenu Level Script

var score : int = 0;

var ScoreText : Text;

private var MainScore : int = 0;


function Start ()
{
  
    score = PlayerPrefs.GetInt("Score", score);
  
    MainScore = PlayerPrefs.GetInt("MainScore", score);
}

function Update ()
{
  
    ScoreText.text = "Score :" +  score;
    //ScoreText.text = "Score :" +  MainScore;
  
  
    if (score >=10)
    {
        PlayerPrefs.SetInt("MainScore", MainScore);
    }
  
    if (score >=150)
    {
        gameObject.Find("Main Camera").SendMessage("Unlock1");
        PlayerPrefs.SetInt("MainScore", score);  
    }
}

Saved From PlayLevel Script

function SaveScore ()
{
    PlayerPrefs.SetInt("Score", score);
}
