I want to create a system where you can earn points, which are saved in between playing separate games. Is there like a way to create a points database?
do you mean like minigames?
You can have each game increment a seperate property, and when you want to see all your points combined, you can just add up all those properties?
You could have a place to enter a save code that preloads stats if you want to truly have it be a separate game.
It is pretty hard to do where you need to have players remember a save number. You can read more about it here!
