I am wanting to save a score of which in my game is known as jelly beans. These jelly beans can be spent as a virtual currency, and so will also be influenced by in-app purchases at some point.
So my question is what is the best way to do this. First-time players of the game will start with a jelly bean total of 0. Each time the player levels up they get 10 Jelly Beans. These will need to be added to the overall virtual currency so that this can be spent.
If the player is returning to the game the current total of jelly beans should be displayed and this will increment as usual.
My code is as shown:

// Set SKNodes

currently the endGame() function only resets the game, in the future it will take you to gameover scene. i hope you can help and if you need any more information please do not be afraid to ask.
