Hello! I need to make a skin shop in my android game. No clue how to save current inventory and how to organize shop system at all. I save the current amount of coins in the PlayerPrefs “Cash”, skins are located in Assets/Resources with names 1, 2, 3…
P.S. I think that saving data in PlayerPrefs is not safe, so I’ll be thankfull if you write are there any another ways of saving data? Maybe GooglePlay provides something? 
Here is a handy inventory tutorial:

I have no idea what this even means. What is unsafe about it? In six years of daily use I haven’t noticed anything “unsafe.”
