Problem with world coordinates in scripts?

I’ve been working on a little 2D test project, but I have a slight problem. when I rotate the platform it goes along local coordinates which I don’t want. So I went off and found Space.World. Now when I try to add this into my script, well. I don’t know where to put it.

Sorry for the stupid question.

Here’s my code:

#pragma strict 
var MoveSpeed:int = 20;
var RotateSpeed:int = 150;
 //movement
 function Update () {
 if(Input.GetKey("w")){
   transform.Translate(Vector3.up * Time.deltaTime * MoveSpeed);
   }
   if(Input.GetKey("d")) {
   transform.Translate(Vector3.right * Time.deltaTime * MoveSpeed);
 }
 if(Input.GetKey("a")) {
   transform.Translate(Vector3.left * Time.deltaTime * MoveSpeed);
}
if(Input.GetKey("s")) {
   transform.Translate(Vector3.down * Time.deltaTime * MoveSpeed);
   
  //Rotation
}
if(Input.GetKey("z")) {
   transform.Rotate(Vector3.forward * Time.deltaTime * RotateSpeed);
}
if(Input.GetKey("c")) {
   transform.Rotate(Vector3.back * Time.deltaTime * RotateSpeed);
   }
}

Thanks for any help!

If you want to rotate relative to the world axis:

transform.Rotate(Vector3.forward * Time.deltaTime * RotateSpeed, Space.World);

transform.Rotate(Vector3.back * Time.deltaTime * RotateSpeed, Space.World);
