I have seen it recommended somewhere in the comments but I want to shed some more light on this game: What Remains of Edith Finch. It is a walking simulator that should take about 2 hours and is best played in a single session.

As Edith Finch, you go back to the house where you grew up in your younger years to explore it. The Finch family has an almost genetic trait of bad luck; many of them have died before their time. You explore the house room by room and explore that person's last moments.

There is no gore or horror of any kind, but there are children that die, so if that is a trigger I would sit this one out. If not, it is currently on sale for less than €5. It is worth it.
