Problems with clicking an object with my script

So I have a seriously dumb issue with my script where you have to click the bottom of the object (circle in this case) to get the object to disappear but your suppose to be able to click any part of the circle for it to disappear. There seems to be a problem with collision precision. By the way, this is built for mobile devices. Here is the code to give you an idea.

 using UnityEngine;
 using System.Collections;
 
 public class FalloutBallScript : MonoBehaviour {
 
     public float terminalVeclocity = -10;
 
     private CircleCollider2D clickCollider;
 
     private bool isBomb = false;
 
     private int score = 1;
     private float speed;
 
     void Start()
     {
         clickCollider = gameObject.AddComponent<CircleCollider2D>();
         clickCollider.radius = gameObject.GetComponent<CircleCollider2D>().radius * 1.4f;
         clickCollider.isTrigger = true;
         float randNum = Random.Range(0f, 1f);
         if (randNum <= .1) isBomb = true;
         if (isBomb)
         {
             renderer.material.color = Color.red;
             gameObject.tag = "Bomb";
         }
         rigidbody2D.gravityScale = Random.Range(.85f, 1.1f);
         Vector2 newVel = new Vector2(Random.Range(-1f, 1f), rigidbody2D.velocity.y);
         speed = Random.Range(2f, 8f);
         rigidbody2D.velocity = newVel * speed;
     }
 
     void FixedUpdate()
     {
 
         if (!FalloutGameControllerScript.gameOver)
         {
             foreach (Touch t in Input.touches)
             {
                 Vector2 tPos = Camera.main.ScreenToWorldPoint(t.position);
 
                 if (t.phase == TouchPhase.Began)
                 {
 
                     if (clickCollider.bounds.Contains(tPos))
                     {
                         if (isBomb) FalloutGameControllerScript.gameOver = true;
                         else
                         {
                             FalloutGameControllerScript.score += score;
                         }
                         Destroy(gameObject);
                     }
                 }
             }
 
             Vector2 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
 
             if (Input.GetMouseButtonDown(0))
             {
                 if (clickCollider.bounds.Contains(mousePos))
                 {
                     if (isBomb) FalloutGameControllerScript.gameOver = true;
                     else
                     {
                         FalloutGameControllerScript.score += score;
                     }
                     Destroy(gameObject);
                 }
             }
         }
 
         if (rigidbody2D.velocity.y < terminalVeclocity)
         {
             rigidbody2D.velocity = new Vector2(rigidbody2D.velocity.x, terminalVeclocity);
         }
 
     }
 
 }
