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;
}

You can do this with a trigger, check out this 1 for more information.
