Help displaying Best Distance in death screen.

Hi all. I am trying to have the highest distance covered to be displayed upon death. I have the displayed distance for when they die, just want the system to keep hold and pull the best distance.

I am not sure what I am missing. It displays "Best Distance: 0m" no matter what. Please see uploaded PDF for full script.

This is the portion I am putting it. It only should display when the death screen comes up which it does, but doesn't show overall highscore.

public void HitHazard()
{
canMove = false;
_canMove = false;
PlayerPrefs.SetInt("CoinsCollected", coinsCollected);
//deathScreen.SetActive(true);
deathScreenCoins.text = coinsCollected + " coins!";
deathScreenDistance.text = Mathf.Floor(distanceCovered) + "m";
if (distanceCovered > highscore)
{
highscore = PlayerPrefs.GetInt("distanceCovered");
PlayerPrefs.SetInt("highscore", highscore);
highscoreText.text = "Best Distance: " + highscore + "m";
}
StartCoroutine("ShowDeathScreen");
}

 

I think you forgot to save your PlayerPrefs. You can do this with PlayerPrefs.Save();

Moreover, if this was not the Problem, you could display your PlayerPrefs with this light and free Editor inside the Unity Editor (as window) and so you will see, if the PlayerPrefs are stored correctly:
