So for my breakout-style game, I have a level select screen with a small preview picture of the level, along with a button to go to that level (frame). However, I want to make it so the game will save and load your progress. I also want it so when you first start the game, every level EXCEPT level 1 will be locked, and the picture will be grayed out. And as you go, you will unlock levels. How could I go about this? I know that INI is used for saving but have no idea how to actually set it up.
