I'm using PlayerPrefs to "save" the player's progress throughout the game. It basically just stores the character's location when a checkpoint is reached, and maintains any characters that have been unlocked. I recently learned that PlayerPrefs will retain their information even when the game closes, so that's great!
I'm curious if there are methods for creating "sets" of player prefs, or in other words, different "saved games" so that there can be multiples within the game, which can then be loaded from a start menu depending on who's playing the game.
