I haven't experimented with it yet, but before I do, I thought I could get pointed into the right direction (or old forum post).
Is it possible, or in what way do you workaround the issue, to save data in such a way that it is hidden for the user of your game?
(hidden, in such a way that it is not easy to just open a text-file, that contains saved data, to alter the current progress of the game)
For example:
- main menu has an option: sound on/off.
- level progress of a character, in an rpg-game.
Thanks in advance.
