In this video, I show how to make a Save & Load system work across multiple scenes in Unity. The tutorial demonstrates this by adding a main menu scene and allowing the player to start a new game or continue a saved game.

The Save & Load system used in this tutorial was created in a previous tutorial that can be found here - https://www.youtube.com/watch?v=aUi9aijvpgs&t

Thank you for watching and I hope the video was helpful! ?
