Alright, I knew it had some kind of order. Weird thing is that the Good ending is separated from the True by Roxy's AI being alive or not. Quite literally, if the AI survives it will always be the Good ending you get. Kinda strange given you don't need to kill anyone to successfully save everyone. They would each get their own body and won't need to clash with anyone. So I don't really understand why Roxy's AI has to die for the True ending.
Lillith seems so vague of a character to me. I wish she had more presence and direct involvement in a game for me to understand why Mr. Black chose her as his partner. I mean Zero and Lexy are house wife material.
