"So the guy who created Adventure, a man named Warren Robinett, decided to hide his name inside the game itself. He hid a key in one of the game’s labyrinths. If you found this key, a small pixel-sized gray dot, you could use it to enter a secret room where Robinett had hidden his name." On the TV, Halliday guides his square protagonist into the game’s secret room, where the words CREATED BY WARREN ROBINETT appear in the center of the screen.
