The game saves automatically every few minutes, and it also keeps backups of older saves (the backups are meant to be used if something goes awry and the main file gets corrupted).
And yes, this is the point of iron gauntlet . I have considered allowing manual saving but haven't made up my mind yet. Though, as mentioned in my latest Post, I'm currently porting the game out of Unity, so any changes will take a while to be released.
