I want to save the level number, so i can read it again later when the person plays the game later again. is there a way to do this in unity?

For very simple stuff like this, use

PlayerPrefs.SetInt("CurrentLevel", [level number here]);

And then when you go to load the level, use

Application.LoadLevel(PlayerPrefs.GetInt("CurrentLevel"));
