There is no way to save the game and return to where you left off. Instead there are only a few points where the game is auto-saved. If you finish the game with the bad ending and would like to try to get a different ending you would have to start the game all over from the beginning! Needless to say, this is a problematic design choice for anyone with a somewhat busy schedule. However, if you have no real world obligations, don't value your time and like repetitive tasks, this might be the right game for you.
