Here's my "SaveSystem":
using System.IO;
using UnityEngine;
using System.Runtime.Serialization.Formatters.Binary;
[System.Serializable]
public static class SaveSystem
{
public static void SavePlayer (BallLaunch saver)
{
BinaryFormatter formatter = new BinaryFormatter();
string path = Application.persistentDataPath + "/player.golfthingy";
FileStream stream = new FileStream(path, File$$anonymous$$ode.Create);
LevelCompleted data = new LevelCompleted(saver);
formatter.Serialize(stream, data);
stream.Close();
}
public static LevelCompleted LoadPlayer()
{
string path = Application.persistentDataPath + "/player.golfthingy";
if (File.Exists(path))
{
BinaryFormatter formatter = new BinaryFormatter();
FileStream stream = new FileStream(path, File$$anonymous$$ode.Open);
LevelCompleted data = formatter.Deserialize(stream) as LevelCompleted;
stream.Close();
return data;
}
else
{
Debug.LogError("Save file not found in " + path);
return null;
}
}
}

I don't see the 'LevelCompleted' class in your source, but I will assume that it derives from MonoBehaviour? Anyway the exception above says that you are trying to use the .net serializer to serialize a MonoBehaviour, which is not allowed ('not marked as serializable' part). Also, the deserialization would be tricky, as you shgould not call its constructor directly (or from the deserializer), but call AddComponent() instead. Try to create the monoBehaviour externally, and just fill it with deserialized data. You can also write surrogates for the serializer, a way to provide a custom handling code for the unknown / non-serializable classes. See the .net docs for the serialization.
