Game Maker Studio: How to Save & Load Coins you Pick Up, Room, & Score?
0GMS File: https://rb.gy/kg1fz7
Note: Do not make global objects (Blue Question Marks) Persistent, because this game uses Test Instance Count for each room. This drop in works like this, once you collect all coins, it will jump to the next room. Well... if you set the global objects to Persistent, the last room will come up error, due to the fact, there are no coins in room. So last room will never show up, so don't make global objects Persistent. So the last room will have no global objects, with Persistent not checked. Note: You can mark global objects Persistent, and load and save will work, but do not use Test Instance Count and you should be okay.

ini_open("coin14.ini") ///Can change the name to what you want the save ini file as. If you want to start from beginning, before the save, just change out all the coin14's to like coin15, coin16, so the change happens and you restart the game.
