• This game is interesting and pretty easy for achievements.
  
• You can get all achievements by finishing it several times without saving and picking all options OR make save files during some scenes and reload them after to make other choices and get different outcomes.
  
• Here I will post three separate endings and one walkthrough with save files (I didn't check it out but I suppose it should work anyway).
