How to make a Save & Load System in Unity

In this video, I show how to make a Save and Load system in Unity that will work for any type of game. We'll save the data to a file in both a JSON format as well as an encrypted format which we'll be able to toggle between in the Unity inspector. *IMPORTANT:* For WebGL games, because WebGL can't save directly to a file system, a different method of storage than we use in the video needs to be implemented. See the pinned comment for more info on this. *IMPORTANT:* Some have mentioned having trouble with Unity versions prior to 2020. I'm not sure on the details, but if you're having issues with the serialization parts of this tutorial, upgrading your Unity version (to 2020 or higher) is something worth trying!
