Need some help

Hey everyone! I'm currently working on making a game with my brother. We are new to MMF2, and are using the demo. The game we are making is a Legend of Zelda (NES)-esque game. I made a platformer before, but it was not nearly as complex. We need to figure out how to use arrays to save objects throughout the changing of frames (such as saving when a secret is found. Right now we have a hidden room with money in it, but there is nothing stopping the player from going into the room over and over for money). I've tried to read up on some tutorials and such, but nothing is making sense. The goal is to have a functional save feature and to have each frame saved upon leaving and loaded upon entering to keep the world consistent (saving secrets found, monsters killed, and so forth). Could anyone help us figure out arrays?

While reading tutorials is very helpfull, you might also want to pick up a few examples, which in my opinion is even more helpfull, though im not sure whetever you would be able to open some of them with a demo version.

One tip that I would have liked to have known as a beginner is how to use Global Values. They are perfect for storing information, can be spread across all frames, and can be saved through an INI.
