I’ve matched the code exactly as the tutorial but I’m still getting this error and can’t complete the game.

Assets\Scripts\MoveLeft.cs(8,13): error CS0246: The type or namespace name 'PlayerController' could not be found (are you missing a using directive or an assembly reference?)

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

public class MoveLeft : MonoBehaviour
{
    private float speed = 30;
    private PlayerController playerControllerScript;

    // Start is called before the first frame update
    void Start()
    {

        playerControllerScript = GameObject.Find("Player").GetComponent<PlayerController>();

    }

    // Update is called once per frame
    void Update()
    {
        if (playerControllerScript.gameOver == false) 
        {
            transform.Translate(Vector3.left * Time.deltaTime * speed);                            
        }
    }
}
