Game Shop/Store

The title says it all, but i wanna know how can i store the coins being collected by the players and later on use it to buy some item in my game and also subtract the collected coins if the player decided to buy new item. (If you are familiar with pen apple game from Ketchapp, You can collect coins and use it to buy pens. That's what i want to achieve)

This is a mobile game and im not pertaining to In-App purchases, I just want an "In game shop" where players can collect coins and buy items using it

The number of collected coins will be a global variable, consistent across the game, and you can save these values using local storage. When the player loads the game again you load the save game and all of the values. The shop would just be some UI that subtracts a number of coins from the global variable.

I made a perfect example of this here.

Great I'am glad that it works for you. Saving is one of the toughest parts of game making so thats why I always look for a way to simplify it.
