        Check if you broke your highscore and set new highscore if you did
        if(m_scores.m_Score > m_scores.m_HighScore)

        Turn on the start button and freeze time if you die
        if (m_scores.m_GameOver)
        {
            Time.timeScale = 0;
            m_startButton.SetActive(true);

            Time.timeScale = 1;
        }
    }

    Spawn the circles with a random amount, random positions (the random color is set in the ball script itself)
    private IEnumerator SpawnBalls()
    {
        while (true)
        {
            int _amount = Random.Range(1, 4 + ((int)m_scores.m_BallSpeed));
            for (int i = 0; i <= _amount; i++)
            {
                int _randomX = Random.Range(-4, 5);
                float _randomY = Random.Range(5.5f, 7);
                Vector3 _ballPos = new Vector3(_randomX, _randomY, 0);
                Instantiate(m_ballPref, _ballPos, Quaternion.identity);
            }
            yield return new WaitForSeconds(m_spawnSpeed);
        }
