I've completed the game but want to play through it again but don't want to lose my current game that is saved. I'm looking at it and think it is saved to my profile as there are no slots to save a game. I'm thinking, if I started a new game and saved it, it would overwrite my current game that I wish to keep.

Is there a way to have two save games? I'm thinking adding another profile and having the same game associated with that profile then my current one might work but I haven't tried that yet.
