In my unity game I've arrange different platform ,when my player collide with upper part of the platform so platform falling down but issue that when my player collide to platform buttom of part so platform falling down.

 void OnCollisionEnter2D(Collision2D target)
 {
         if (target.gameObject.tag == "Player") {
         gameObject.GetComponent<Rigidbody2D> ().isKinematic = false;
     }
 }

Check to see if the player is falling, or rising. Also, it's a good idea to set up a reference to your components as GetComponent() is very slow.

 Rigidbody2D rb;
 
 
 void Start ()
 {
     rb = GameObject.FindWithTag ("Player").GetComponent <Rigidbody2D>();
 }
 
 
 void OnCollisionEnter2D (Collision2D target)
 {
     if (target.gameObject.tag == "Player") 
     {
         if (rb.velocity.y <= 0)
             gameObject.GetComponent<Rigidbody2D> ().isKinematic = false;
             else
             return;
     }
 }

(You may have to change the = I can't remember if velocity pulls down, or up)
