        {
            SceneManager.LoadScene("Level2");
        }

Answer 1

This code does not work when you have defined a list. In fact, a list with zero members is not equal to null. null means no list definition.

enemies == null;

Change the code this way:

if (enemies.Length == 0)
{
    SceneManager.LoadScene("Level2");
}
