“Games a bit like those from Team Ico” is surely a genre by now. Games in which ghostly-pale, solitary and/or mute people wander around large, man-made but abandoned structures, ostensibly solving environment puzzles but mainly creating feelings of loneliness and longing. If Alice were here, she’d add “’em up” at the end of that sentence.
MARE [official site], then, is a loneliness and longing ’em up designed for Oculus VR in which, yeah, all of the above happens as you control a little girl and a mechanical bird. The trailer looks quite lovely.
