How do I make my game end when something comes near the player?

I am making a game like Slender. The enemy comes towards the player like it should do, but the player does not die. I want to make it so that when the enemy comes into a certain radius of the player, another scene is loaded (which will have a cut scene). This is my script:

 var target : Transform;
 var moveSpeed = 3;
 var rotationSpeed = 3;
 var myTransform : Transform;
 
 function Awake(){
 myTransform = transform;
 }
 
 function Start () {
 target = GameObject.FindWithTag("Player").transform;
 }
 
 function Update () {
 myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
 
 Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
 
 myTransform.position += myTransform.forward*moveSpeed*Time.deltaTime;
 }
