    Input.mousePosition), Vector2.zero);

    // When the target layer is hit
    if (hit.collider != null && hit.collider.gameObject == gameObject)
    {
        transform.localScale = new Vector3(1.2f, 1.2f, 1); // Enlarge the object
    }
    else
    {
        transform.localScale = new Vector3(1, 1, 1); // Restore the object's scale
    }

    if (Input.GetMouseButtonDown(0))

        // Mouse button pressed while the target layer is hit
        if (hit.collider != null && hit.collider.gameObject == gameObject)
