The screen hums softly. A big red button on the controller catches my eye as I press it with my thumb. The world inside flickers and resets—no harm done. I try again, this time pressing both buttons at once. The screen goes black for a second, then blinks back to life. The game still goes wrong after that, but now when it does, I know how to make it start over neatly. Every time it gets stuck, I try different button combinations until the characters and monsters zoom right into action again. It’s like magic, making the screen do what I want by pressing buttons just so.
