is there a good ending ?
If you, by chance, are asking if there's any completed routes, I'm afraid not.
All bad endings currently in the game can be avoided. If your asking because you can't save a certen someone I will say there is one password so far that's not out right given to you like the others you will need to really think about what what's being said to you after the event. Do what I did and take notes of things others say. They may come in handy.
