how to keep an animation condition after Application.loadLevel

So I finished the Roguelike 2D tutorial completely and decided to test my knowledge by expanding upon the finished product. Currently I've created a shotgun that has a 10% chance of spawning whenever a level is loaded. Ive made an animation for the player so when he picks up the shotgun, his idle animation turns into a new idle animation of him holding the shotgun. This all works fine until I advance the level.

There is a boolean condition that decides what animation is playing, and when the game reloads the scene, the boolean resets itself. I've spent countless hours and different attempts to try and keep the boolean variable past the level exit but to no avail. Can somebody please tell me how to keep that data through the Restart function?

Here is the GameManager.cs file.

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine.UI;
 
 public class GameManager : MonoBehaviour {
 
     public float levelStartDelay = 2f;
     public float turnDelay = .1f;
     public static GameManager instance = null;
     public BoardManager boardScript;
     public int playerFoodPoints = 100;
     [HideInInspector] public bool playersTurn = true;
 
 
     private Text levelText;
     private GameObject levelImage;
     private int level = 1;
     private List<Enemy> enemies;
     private bool enemiesMoving;
     private bool doingSetup;
     public Animator animator;
 
 
     // Use this for initialization
     void Awake () 
     {
         if (instance == null)
             instance = this;
         else if (instance != this)
             Destroy (gameObject);
 
         DontDestroyOnLoad (gameObject);
         enemies = new List<Enemy> ();
         boardScript = GetComponent<BoardManager> ();
         InitGame ();
     }
 
     private void OnLevelWasLoaded (int index) {
 
         level++;
 
         InitGame ();
     }
 
     void InitGame()
     {
         doingSetup = true;
 
         levelImage = GameObject.Find ("LevelImage");
         levelText = GameObject.Find ("LevelText").GetComponent<Text> ();
         levelText.text = "Day " + level;
         levelImage.SetActive (true);
         Invoke ("HideLevelImage", levelStartDelay);
 
         enemies.Clear ();
         boardScript.SetupScene (level);
     }
 
     private void HideLevelImage () {
     
         levelImage.SetActive (false);
         doingSetup = false;
     
     }
 
     public void GameOver () {
 
         levelText.fontSize = 24;
         levelText.text = "You met your end after " + level + " days.";
         levelImage.SetActive (true);
         enabled = false;
 
     }
     
     // Update is called once per frame
     void Update () {
 
         if (playersTurn || enemiesMoving || doingSetup)
             return;
 
         StartCoroutine (MoveEnemies ());
     
     }
 
     public void AddEnemyToList(Enemy script) {
     
         enemies.Add (script);
     }
 
 
 
     IEnumerator MoveEnemies() {
 
         enemiesMoving = true;
         yield return new WaitForSeconds(turnDelay);
         if (enemies.Count == 0) {
 
             yield return new WaitForSeconds(turnDelay);
         }
 
         for (int i = 0; i < enemies.Count; i++) {
 
             enemies[i].MoveEnemy ();
             yield return new WaitForSeconds (enemies[i].moveTime);
         }
 
         playersTurn = true;
         enemiesMoving = false;
     }
 }
