Odpowiada za menu w grze. Game posiada w sobie kilka różnych obiektów Menu z innymi opcjami. Funkcja Reload określa umiejscowienie elementów na podstawie podanego typu Menu, jak i ilości elementów jakie on zawiera. No podstawie wciśniętych przycisków zmieniana jest pozycja aktualnie wybranego elementu, a po wciśnięciu Enter element kopiowany jest do zmiennej selected z której skorzysta potem Game. Dla klawisza Backspace ustawiana jest zmienna remove, która mówi Game jaki element ma zostać usunięty. GetPosition używane jest przez Game przy wyświetlaniu zapisów gry oraz ich daty modyfikacji.
