[Help] hey i'm just a beginner... Problem with WEB GL build

So i'm programming a block breaker game and i'm already finished. Ican play without a problem on Unity but once i build it and run it for WEB GL the game won't let me break the blocks.

Please help!!!

This is my code for the block:

 using UnityEngine;
 using System.Collections;
 
 public class Brick : MonoBehaviour {
 
     public AudioClip crack;
     public Sprite[] hitSprites;
     public static int breakableCount = 0;
     public GameObject smoke;
     
     private int timesHit;
     private    LevelManager levelmanager;
     private bool isBreakable;
     
             // Use this for initialization
     void Start () {
         isBreakable = (this.tag == "Breakable");
         // Keep track of breakable bricks
         if (isBreakable){
             breakableCount++;
         }
         timesHit = 0;
         levelmanager = GameObject.FindObjectOfType<LevelManager>();
     }
     
     // Update is called once per frame
     void Update () {
         
     }
     
     void OnCollisionExit2D (Collision2D col){
         AudioSource.PlayClipAtPoint (crack, transform.position,0.25f);
         if (isBreakable){
             HandleHits();
         }
     }
     
     void HandleHits (){
         timesHit++;
         int maxHits = hitSprites.Length + 1;
         if(timesHit >= maxHits){
             breakableCount--;
             levelmanager.BrickDestroyed();
             Puff ();
             Destroy(gameObject);
         } else{
             LoadSprites();
     }
     }    
     void Puff (){
             GameObject smokePuff = Instantiate (smoke,transform.position,Quaternion.identity) as GameObject;
             smokePuff.GetComponent<ParticleSystem>().startColor = gameObject.GetComponent<SpriteRenderer>().color;
         }
         
     
     void LoadSprites () {
         int spriteIndex = timesHit - 1;
         if (hitSprites[spriteIndex] != null){
         this.GetComponent<SpriteRenderer>().sprite = hitSprites[spriteIndex];
         } else {
             Debug.LogError ("Brick Sprite Missing");
         }
     }
     
     //TODO remove this method once we can actually win
     void SimulateWin (){
         levelmanager.LoadNextLevel();
         
     }
 }
