Hi Din! Thanks for the fast response!
I have two saved files; One is the automatic save at day 20 Morning the other is day 20 Night (when ask to you for saving).
I played to the end, got a relationship with the Commander and saw the credits and Epilogue and the hilarious last secret scene :'D.
But the start menu is always the same with the four options avaliable; Continue, New Game, Load Game and Gallery and the prinicipal background image.
