Thank you for the game and for sharing your personal experience!
Despite the subject of the story, I can't say that I've felt sad when playing it. Rather, the game made me feel somewhat indifferent at the beginning, but slowly grow me more and more interested in details of the complex family relations and why everything is happening the way it is. I especially liked segments when I was allowed to just talk to different people and explore their reactions. I wish this type of storytelling was more of the focus of the game, but I understand that character dialogs and narration was needed to emotionally ground player in the story.
With that said, I felt a bit of a dissonance between exploration segments and story segments. Talking to everybody on the funeral felt out of the character, as it was established during the dialog sequences.
