Frog can move before the Spacebar is pressed

Hello all,

I'm almost there with the game. I can play the game fully and the game states work, but when testing the game, I can see that the frog can be moved before the space bar is pressed and of course the camera doesn't follow it until I do. I'm pretty sure what's not supposed to happen.

There were a couple of Red errors in the console but those have now disappeared.

I know that everything else is working because the bird doesn't chase the frog until the spacebar is pressed even after the first go and the game is back in the Start State.

Here's my code. :)

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEngine.SceneManagement;


public class GameState : MonoBehaviour {

    private bool gameStarted = false;

    [SerializeField]
    private Text gameStateText;
    [SerializeField]
    private GameObject player;
    [SerializeField]
    private BirdMovement birdMovement;
    [SerializeField]
    private FollowCamera followCamera;


    private float restartDelay = 3f;
    private float restartTimer;
    private PlayerMovement playerMovement;
    private PlayerHealth playerHealth;


    // Use this for initialization
    void Start () {


        Cursor.visible = false;

        playerMovement = player.GetComponent<PlayerMovement> ();
        playerHealth = player.GetComponent<PlayerHealth> ();

        //prevent the player from moving tbatth start of the game
        playerMovement.enabled = false;
        //prevent the bird from moving at the end of the game
        birdMovement.enabled = false;
        //prevent the follow camera from moving into its game position
        followCamera.enabled = false;


    }

    // Update is called once per frame
    void Update() {
        //If the game is not started and the player presses the space bar... 
        if(gameStarted == false && Input.GetKeyUp(KeyCode.Space)) {

            //start the game
            StartGame();    
        }

        if(playerHealth.alive == false) {
            //end the game
            EndGame();

            //increment a timer to count up to restarting
            restartTimer = restartTimer + Time.deltaTime;

            //..and if it reaches the restart delay...
            if(restartTimer >= restartDelay) {

                // ...then  reload the currently loaded level
                //Application.LoadLevel(Application.loadedLevel);
                SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
            }
        }


    }

    private void StartGame() {

        //set the game state
        gameStarted = true;

        //Remove the start text
        gameStateText.color = Color.clear;

        //Allow the player to move
        playerMovement.enabled = true;

        //Allow the bird to move
        birdMovement.enabled = true;

        //Allow the camera to move;
        followCamera.enabled = true;
    }

    private void EndGame() {
        //set the game state
        gameStarted = false;

        //Show the game over text
        gameStateText.color = Color.white;
        gameStateText.text = "Bad Luck! Game over";

        //Remvoe the player from the game
        player.SetActive(false);
    }
