Sprites rotating around Z axis when they shouldnt be.

Hi,

I have a script where a sprite will follow the player. It works, other than the sprite rotating around the Z axis.

Can someone help me with trying to make it 2D and not spin around the Z axis please.

This is the code that is controlling the movement:

Thanks

 void Start()
 {
     myTransform = transform;
     player = GameObject.FindGameObjectWithTag("Player").transform;
 }
 
 void Update ()
 {
     
     player = GameObject.FindGameObjectWithTag("Player").transform;
         
         follow=true;
     
     if(follow && player != null)
     {


         myTransform.rotation = Quaternion.Slerp(myTransform.rotation, Quaternion.LookRotation(player.position - myTransform.position), rotationSpeed * Time.deltaTime);
         myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;


         }

     }
