Build a game from GED files?

Hi everybody!
I'm making a exciting and funny game building it from GED files, but than making 4 levels i'm considering:
how i do save into the game
?
So, i'm playing, exit the game, open it again and i wanna continue where i stopped.
Is there any mode to controlling a GED file into an another?
Thanx for helping!
