Normal mode refers to the common, initially released version of Those Nights at Rachel's, released fully on February 5, 2016. A demo had been released not long before on January 23, 2016. Due to criticism about the game's glitches and somewhat unpredictable difficulty curve, a harder version was released afterwards on the next day, February 6, 2016, featuring a higher difficulty and a darker atmosphere making it more difficult to observe the animatronics' movements throughout the restaurant.
