This is a thoughtful game, a mostly-linear ghost story about a roommate that haunts the place and about relationships and our dealings with the others.
I liked the writing in this, it's really about turning an inner eye on ourselves and seeing the bad habits and unhealthy relationships that we have let become so natural that we can't even see them anymore.
It also has an interesting take on ghosts, similar to but slightly different from most representations I've seen in media.
