Is there a way to save a game in progress? After being exported to a stand alone game, The player/s should be able to close the game and open it to the same place/setup/move at a later time. This is a longer game,and may not be finished in one sitting.
You have to write your own system. I tend to use json to encode data, but other people like pythons pickle module.

If you clarify your question, we can probably help more.
