How many chances should you give a game before you decide it’s just not clicking with you? That’s what I asked myself every time I booted up the Game Bakers’ Cairn. A lot of games make you climb, but few have ever required me to be as intentional with every single movement as I scaled their cliffs. Cairn, meanwhile, makes you move all four of heroine Aava’s extremities independently, which is what makes the game challenging, and often maddening. Movement is clunky in Cairn, and movement is what you do in this game.
