2d roguelike tutorial board manager issues

Hey folks, I’m on lesson 5 of the 2d roguelike tutorial (see here) and when I play the scene after building the test game manager script I’m getting some really odd results:

You might not be able to tell, but I think it’s rendering correctly as far as outer wall, inner walls, food, enemies, etc. but the spacing is so out of whack it’s crazy. When I thought it was a code issue I went to the previous lesson and copy/pasted it into my boardManager file and got the exact same results. I’ll post them here for reference:

Board Manager:

    using UnityEngine;
    using System;
    using System.Collections.Generic;       //Allows us to use Lists.
    using Random = UnityEngine.Random;      //Tells Random to use the Unity Engine random number generator.
    
    namespace Completed
    
    {
    
    	public class BoardManager : MonoBehaviour
    	{
    		// Using Serializable allows us to embed a class with sub properties in the inspector.
    		[Serializable]
    		public class Count
    		{
    			public int minimum;             //Minimum value for our Count class.
    			public int maximum;             //Maximum value for our Count class.
    
    
    			//Assignment constructor.
    			public Count (int min, int max)
    			{
    				minimum = min;
    				maximum = max;
    			}
    		}
    
    
    		public int columns = 8;                                         //Number of columns in our game board.
    		public int rows = 8;                                            //Number of rows in our game board.
    		public Count wallCount = new Count (5, 9);                      //Lower and upper limit for our random number of walls per level.
    		public Count foodCount = new Count (1, 5);                      //Lower and upper limit for our random number of food items per level.
    		public GameObject exit;                                         //Prefab to spawn for exit.
    		public GameObject[] floorTiles;                                 //Array of floor prefabs.
    		public GameObject[] wallTiles;                                  //Array of wall prefabs.
    		public GameObject[] foodTiles;                                  //Array of food prefabs.
    		public GameObject[] enemyTiles;                                 //Array of enemy prefabs.
    		public GameObject[] outerWallTiles;                             //Array of outer tile prefabs.
    
    		private Transform boardHolder;                                  //A variable to store a reference to the transform of our Board object.
    		private List <Vector3> gridPositions = new List <Vector3> ();   //A list of possible locations to place tiles.
    
    
    		//Clears our list gridPositions and prepares it to generate a new board.
    		void InitialiseList ()
    		{
    			//Clear our list gridPositions.
    			gridPositions.Clear ();
    
    			//Loop through x axis (columns).
    			for(int x = 1; x < columns-1; x++)
    			{
    				//Within each column, loop through y axis (rows).
    				for(int y = 1; y < rows-1; y++)
    				{
    					//At each index add a new Vector3 to our list with the x and y coordinates of that position.
    					gridPositions.Add (new Vector3(x, y, 0f));
    				}
    			}
    		}
    
    
    		//Sets up the outer walls and floor (background) of the game board.
    		void BoardSetup ()
    		{
    			//Instantiate Board and set boardHolder to its transform.
    			boardHolder = new GameObject ("Board").transform;
    
    			//Loop along x axis, starting from -1 (to fill corner) with floor or outerwall edge tiles.
    			for(int x = -1; x < columns + 1; x++)
    			{
    				//Loop along y axis, starting from -1 to place floor or outerwall tiles.
    				for(int y = -1; y < rows + 1; y++)
    				{
    					//Choose a random tile from our array of floor tile prefabs and prepare to instantiate it.
    					GameObject toInstantiate = floorTiles[Random.Range (0,floorTiles.Length)];
    
    					//Check if we current position is at board edge, if so choose a random outer wall prefab from our array of outer wall tiles.
    					if(x == -1 || x == columns || y == -1 || y == rows)
    						toInstantiate = outerWallTiles [Random.Range (0, outerWallTiles.Length)];
    
    					//Instantiate the GameObject instance using the prefab chosen for toInstantiate at the Vector3 corresponding to current grid position in loop, cast it to GameObject.
    					GameObject instance =
    						Instantiate (toInstantiate, new Vector3 (x, y, 0f), Quaternion.identity) as GameObject;
    
    					//Set the parent of our newly instantiated object instance to boardHolder, this is just organizational to avoid cluttering hierarchy.
    					instance.transform.SetParent (boardHolder);
    				}
    			}
    		}
    
    
    		//RandomPosition returns a random position from our list gridPositions.
    		Vector3 RandomPosition ()
    		{
    			//Declare an integer randomIndex, set it's value to a random number between 0 and the count of items in our List gridPositions.
    			int randomIndex = Random.Range (0, gridPositions.Count);
    
    			//Declare a variable of type Vector3 called randomPosition, set it's value to the entry at randomIndex from our List gridPositions.
    			Vector3 randomPosition = gridPositions[randomIndex];
    
    			//Remove the entry at randomIndex from the list so that it can't be re-used.
    			gridPositions.RemoveAt (randomIndex);
    
    			//Return the randomly selected Vector3 position.
    			return randomPosition;
    		}
    
    
    		//LayoutObjectAtRandom accepts an array of game objects to choose from along with a minimum and maximum range for the number of objects to create.
    		void LayoutObjectAtRandom (GameObject[] tileArray, int minimum, int maximum)
    		{
    			//Choose a random number of objects to instantiate within the minimum and maximum limits
    			int objectCount = Random.Range (minimum, maximum+1);

    				Instantiate(tileChoice, randomPosition, Quaternion.identity);
    			}
    		}
    
    
    		//SetupScene initializes our level and calls the previous functions to lay out the game board

    		}
    	}
    }

Game Manager:

using UnityEngine;
using System.Collections;

namespace Completed

{
	
	public class GameManager : MonoBehaviour {

		public BoardManager boardScript;
	
		private int level = 3;
	
		void Awake ()
		{
			boardScript = GetComponent<BoardManager> ();
			InitGame ();
		}
	
		void InitGame()
		{
			boardScript.SetupScene (level);
		}

		void Update() {

		}


	}
}

Any help or guidance would be appreciated! Thanks.
