It's a simple puzzle platformer where you play as a border collie with the second sight protecting their grieving human as she comes to terms with old memories. The puzzles frequently involve finding nature spirits or sprigs of heather to ward off malevolent spirits warping her perception or keeping you on the wrong side of the veil, while a few involve learning how to sheep dog. That's it, that's the entire game. If not you're already sold, it's probably not for you.
