It resembles its predecessor, Shin Onigashima, in its implementation of the "Change Character" command, usage of traditional Japanese fairytales, and general screen layout and appearance.
While Shin Onigashima demanded rather complex puzzle-solving abilities, Yuyuki mainly focuses on having the player carefully read and understand the story-line.
Easy trivia questions and simple action gameplay emerge at certain points, and players may find themselves searching for the obvious answer on screen more often than thinking hard to solve the puzzle at hand.
The shortening in load time after choosing commands, and an overall decrease in difficulty allowed Yuyuki to run at a much quicker tempo than its predecessor.
However, Goku is led away and imprisoned by Oshakasama for the various crimes he has committed, and Chao sets off to find the "Gavel of Light" in order to save him.
An odd commercial for the game was aired prior to its release, featuring real-life versions of the main characters (all wearing sunglasses) visiting various locations by plane in a "Tenjiku Tour" (Tenjiku is the final destination in Journey to the West, located in India) such as Japan, Hawaii and Siberia.
The most striking part was the commercial's jingle; the developers employed a strange song of no particular meaning that chanted the names of the main characters.
