Early childhood is a daunting time, full of unfamiliar experiences, bewildering potential and the very real possibility that there are monsters living under the bed. Murasaki Baby neatly encapsulates all of these characteristics, along with the notion that childhood is when most parents stand as infallible bastions of safety and comfort. As such, your overarching goal is to reunite Baby with her mother, but that's a bit like saying that the point of Journey is to reach the top of a mountain.
Over the course of two and a half hours, this puzzle-platformer goes on to explore parenthood, trust, responsibility and the wrenching realisation that, try as you might, you cannot always keep a child safe from harm. It's affecting but it's also more than a little odd; screenshots will tell you that much but they can't fully convey just how effective Baby's journey is at simultaneously eliciting feelings of protectiveness and bemused unease.
While Murasaki Baby's thematic identity is constantly reaffirmed by these concepts, its mechanical nuts and bolts are inextricably tied to the Vita's unique features and so are occasionally liable to minor hiccups. Guiding Baby by the hand is simply a matter of reaching out via the touch-screen and leading her around as she takes her first tentative steps in a world that has been pulled from some half-remembered fever dream. She can be made to walk or run, but over-stretch her peculiarly elastic arm and she'll tumble to the ground. Then, as she picks herself up, dusts down her small dress and laughs nervously when you reach for her hand once more, you feel sufficiently guilty for making her fall and pledge to do better in future. It's here that the game feels most like an Edward Gorey illustrated guide to parenting.
