This is for an android game.
// General is the name of my script //

Here is the code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;


[System.Serializable]
public class PlayerData
{
    public int red = 0;
    public int yellow = 0;
    public int green = 0;
    public int purple = 0;
    public int black = 0;
    public int white = 0;
    public int cyan = 0;
    public int pink = 0;
    public int orange = 0;

    public int Money;
    public int stars = 0;


    public int Skin01 = 0;
    public int Skin02 = 0;
    public int Skin03 = 0;
    public int Skin04 = 0;
    public int Skin05 = 0;


    public PlayerData (General player)
    {
        red = player.red;
        yellow = player.yellow;
        green = player.green;
        purple = player.purple;
        black = player.black;
        white = player.white;
        cyan = player.cyan;
        pink = player.pink;
        orange = player.orange;

        Money = player.Money;
        stars = player.stars;

        Skin01 = player.Skin01;
        Skin02 = player.Skin02;
        Skin03 = player.Skin03;
        Skin04 = player.Skin04;
        Skin05 = player.Skin05;
    }
}

second script:

using UnityEngine;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
using System;

public static class SaveSystem
{
    public static void SavePlayer (General player)
    {
        BinaryFormatter formatter = new BinaryFormatter();
        string path = Application.persistentDataPath + "/GameSaveData.beans";
        FileStream stream = new FileStream(path, FileMode.Create);

        PlayerData data = new PlayerData(player);

        formatter.Serialize(stream, data);
        stream.Close();
    }

    public static PlayerData LoadPlayer()
    {
        string path = Application.persistentDataPath + "/GameSaveData.beans";
        if (File.Exists(path))
        {
            BinaryFormatter formatter = new BinaryFormatter();
            FileStream stream = new FileStream(path, FileMode.Open);

            PlayerData data = formatter.Deserialize(stream) as PlayerData;
            stream.Close();

            return data;
        } else
        {
            Debug.LogError("Save file not found in " + path);
            return null;
        }

    }

}

my script:

...
...
    private void Awake()
    {
        LoadPlayer();
    }   
...
public void SavePlayerFunc()
    {
        SaveSystem.SavePlayer(this);
    }
    public void LoadPlayer()
    {
        PlayerData data = SaveSystem.LoadPlayer();

        red = data.red;
        yellow = data.yellow;
        green = data.green;
        purple = data.purple;
        black = data.black;
        white = data.white;
        cyan = data.cyan;
        pink = data.pink;
        orange = data.orange;


        Skin01 = data.Skin01;
        Skin02 = data.Skin02;
        Skin03 = data.Skin03;
        Skin04 = data.Skin04;
        Skin05 = data.Skin05;
    }
...
    public void Continue()
    {
        ...//called by a button
        SavePlayerFunc();
    }
...

Just use PlayerPrefs. They work good.
