press play, game objects get deleted, game breaks.

okay so i just finished this script here

 #pragma strict
 
 var maxfalldistance = -10;
 
 function Update () {
 
     if (transform.position.y <= maxfalldistance)
     (
     Debug.Log("test")
     );
     
     (
     Application.LoadLevel("level 1")
     );
 
 }

with no errors in console. i them press play to test my level and all my game objects get deleted and my game ceases to work. after i stop all my game objects come back, still with no errors.

as these pictures show

this is a bug that seems to run in the unity engine but might have something to do with the script. can anyone help?
