How to have different sets of levels?
I'm making an endless runner. I want to make it to where the player can choose what scene they want to play on. For example, say I want to have the following scenes: Forest, Beach, Desert and City. How could i make it to where the player chooses where they want to play (or scene) and then after they choose that they can choose whatever level they want to play on that scene (as long as they've unlocked it? I hope I'm explaining what I'm trying to do right. Thanks for the help!
