The guy's wife died. Then I pressed left until the guy killed himself to be with her.
I'll not wander in the philosophical/psicological matter of the story, everyone thinks the way he/she wants, but this can be barely called "game". It's an interactive movie, when some part of the animation is controlled by the used.
Also, I found pretty "forced" some elements of the story - from the church to the cemetery, the first-meet place was conviniently placed there (like "Hey, I'm a important place to this couple story and I came here so Walter can pass through me and add some more sadness to the story").
The music is nice, I'm giving one star for it.
