Hello! I am making an offline 2D mobile game. I am struggling about the inventory. The player can buy gold with real money. And the player can use the gold to buy items in the game. I just don't know where/how to store the player's inventory (gold and items). Right now it is in a dat file. I was thinking about storing it in a web database, but 250 $ for a month is too much for me. Another solution is a client side database, for example an mdf file. What is the recommended? Or is there a cheaper web database somewhere? And also if the player loses his phone, everything will be lost if I store it on client side. I don't know if this is a huge problem or not. Thanks for the replies!
