Script working in Editor but not in Build

This is a blank project. Just trying to drag a cube. I've seen similar questions on this but I have no idea what I'm looking for.

I build and...nothing.

Main Camera is in Orthographic projection, works fine in Editor, but nothing at all when built. Please help before I start punching myself in the face.

This is literally the only script in this project.

using UnityEngine;

using System.Collections;

public class DraggingScript : MonoBehaviour

{

 //This code is for 2D click/drag gameobject

 //Please make sure to change Camera Projection to Orthographic

 //Add Collider (not 2DCollider) to gameObject  

 public GameObject gameObjectTodrag; //refer to GO that being dragged

 public Vector3 GOcenter; //gameobjectcenter
 public Vector3 touchPosition; //touch or click position
 public Vector3 offset;//vector between touchpoint/mouseclick to object center
 public Vector3 newGOCenter; //new center of gameObject

 RaycastHit hit; //store hit object information

 public bool draggingMode = false;


 // Use this for initialization
 void Start()
 {

 }

 // Update is called once per frame
 void Update()
 {

         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

         //if ray hit a Collider ( not 2DCollider)
         if (Physics.Raycast(ray, out hit))
         {
