Anomalous Coffee Machine 2 is a single-player interactive visual novel built around an uncanny encounter: a mysterious girl, an ordinary-looking vending machine and a drink that can be summoned by typing a word. The girl offers no explanation for herself or the machine. Instead, the game leaves you to investigate their connection through the choices you make.
Its central loop is deliberately spare. Enter a word, receive a cup, then decide whether the girl or you will drink it. Her responses vary with what she is given, while choosing the drink yourself makes the machine react to you. The result may be a smile, a wince, a disappearance or no immediate response at all. The machine accepts even unsettling or impossible requests, turning free-form experimentation into the main way to probe the fiction.
There are no quests, markers or instructions directing that exploration. Its appeal rests on testing words and watching how the girl and machine respond, with the underlying mystery left for players to explore. The listing also identifies Steam Achievements and Save Anytime among its features. [sic]
