Some of this information - like the player's current position - is probably going to be stored as a global variable. Abilities and unlockables might be stored in a global array. If there are lots of items that the player should only be able to collect once, you'll want to use a ds_map to store whether the item was collected.

Then once you have all your data stored in memory, you'll need a way to put it into a save file. Do you know how to do that? (My RPG engine has an example that might help you.)

This is a very simplified outline, so if you're confused about anything, please ask.

Course clear! You got a card.
