Born as twins, Yin (black) and Yang (white) never leave each others side. Yin is cursed of the death touch and Yang is forever clumsy. The twins are nothing alike. The only resemblance they share is their movement which was also cursed upon them at birth. Wherever Yang moves, Yang follows and vise versa. To free them from their curses, they must push 5 red buttons 'til the curse is lifted while avoiding the blue buttons. The red buttons are heavily guarded and whomever seeks to push the red button shall be destroyed.
