Как исправить ошибку в юнити cs0246

Всем привет, дамы и господа! Скопировал я значит код для сохранения данных с одного источника.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;

public static class SaveLoad 
{

    public static List<Game> savedGames = new List<Game>();

    //методы загрузки и сохранения статические, поэтому их можно вызвать откуда угодно
    public static void Save() 
    {
        SaveLoad.savedGames.Add(Game.current);
        BinaryFormatter bf = new BinaryFormatter();
        //Application.persistentDataPath это строка; выведите ее в логах и вы увидите расположение файла сохранений
        FileStream file = File.Create (Application.persistentDataPath + "/savedGames.gd");
        bf.Serialize(file, SaveLoad.savedGames);
        file.Close();
    }

    public static void Load() 
    {
        if(File.Exists(Application.persistentDataPath + "/savedGames.gd")) {
            BinaryFormatter bf = new BinaryFormatter();
            FileStream file = File.Open(Application.persistentDataPath + "/savedGames.gd", FileMode.Open);
            SaveLoad.savedGames = (List<Game>)bf.Deserialize(file);
            file.Close();
        }
    }
}

Мне выдало ошибку
(10,24): error CS0246: The type or namespace name ‘Game’ could not be found (are you missing a using directive or an assembly reference?)

Честно, я вообще не понимаю сути. Сможете помочь?

Go to unity

I have two scripts, one is located at:

Assets / Scriptable Objects / …

while the other one is located at:

Assets / Scripts / …

I have the first script encapsulated on a namespace.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using VoidlessNodes.LevelFlowNodes;

namespace VoidlessUtilities
{
[CreateAssetMenu]
public class LevelFlowData : BaseNodeEditorData<BaseLevelNode, LevelFlowEditorAttributes>
{
    private const string MENU_ITEM_PATH = "Create / ScriptableObjects / LevelFlowData";
    private const string NEW_ASSET_PATH = "ScriptableObjects / Level Flow Data";

    [SerializeField] private string _name;
    private RootLevelNode _root;

    /// <summary>Gets and Sets name property.</summary>
    public string name
    {
        get { return _name; }
        set { _name = value; }
    }

    /// <summary>Gets and Sets root property.</summary>
    public RootLevelNode root
    {
        get { return _root; }
        set { _root = value; }
    }

    [MenuItem(MENU_ITEM_PATH)]
    public static void CreateAsset()
    {
        LevelFlowData scriptableObject = ScriptableObject.CreateInstance<LevelFlowData>() as LevelFlowData;
        AssetDatabase.CreateAsset(scriptableObject, AssetDatabase.GenerateUniqueAssetPath(NEW_ASSET_PATH));
    }

    public BaseLevelFlowNode GetLevelFlow()
    {
        BaseLevelFlowNode rootLevelFlow = null;

        if(root != null)
        {
            rootLevelFlow = root.GetNode();
        }
        else
        {
            Debug.LogError("[LevelFlowData] Data has no RootLevelFlowNode saved");
        }

        return rootLevelFlow as RootLevelFlowNode;
    }
}
}

And the other one is using the same namespace, which is a namespace I use for my custom scripts, but the only difference is that LevelFlowData’s location is not under Scripts.

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using VoidlessUtilities;

public class TestLevelController : Singleton<TestLevelController>
{
    [SerializeField] private LevelFlowData _levelFlowData;
    [SerializeField] private List<GameObject> _testViews;

    /// <summary>Gets and Sets levelFlowData property.</summary>
    public LevelFlowData levelFlowData
    {
        get { return _levelFlowData; }
        protected set { _levelFlowData = value; }
    }

    /// <summary>Gets and Sets testViews property.</summary>
    public List<GameObject> testViews
    {
        get { return _testViews; }
        set { _testViews = value; }
    }

#region UnityMethods:
    void OnEnable()
    {
        BaseInteractable.onTriggeredEvent += (int _eventID, bool _triggered)=> { Debug.Log("[TestLevelController] Event Triggered: " + _eventID); };
    }

    void OnDisable()
    {
        BaseInteractable.onTriggeredEvent -= (int _eventID, bool _triggered)=> { Debug.Log("[TestLevelController] Event Triggered: " + _eventID); };
    }

    /// <summary>TestLevelController's' instance initialization.</summary>
    void Awake()
    {

    }

    /// <summary>TestLevelController's starting actions before 1st Update frame.</summary>
    void Start ()
    {

    }

    /// <summary>TestLevelController's tick at each frame.</summary>
    void Update ()
    {

    }
#endregion

#region PublicMethods:
    public void EnableView(int _index)
    {
        testViews.SetAllActive(false);
        testViews[_index].SetActive(true);
    }
#endregion

#region PrivateMethods:

#endregion
}

Do I need to move LevelFlowData to Scripts, and make platform independet compilation (e.g., #if UNITY_EDITOR) encapsulation for UnityEditor namespace usage? Or is there another point I am missing?

This is the specific error log:

Assets/Scripts/Scene Controllers/TestLevelController.cs(10,27): error CS0246: The type or namespace name `LevelFlowData’ could not be found. Are you missing an assembly reference?

Thanks in advance.
