 public class Touching : MonoBehaviour {

     void OnCollisionEnter2D(Collision2D col)
     {
         if (col.gameObject.tag == "Enemy") {
             SceneManager.LoadScene ("Tutorial Level");

         if (col.gameObject.tag == "Mov Platform")
         this.transform.parent = col.transform;
         }
     }

     void OnCollisionExit2D(Collision2D col)
     {
         if (col.gameObject.tag == "Mov Platform")
             this.transform.parent = null;
     }
