The music in Journey was composed and orchestrated by Austin Wintory, who had previously worked with Thatgamecompany on the soundtrack for Flow. Wintory worked closely on the soundtrack with sound designer Steve Johnson, as well as the programming team, so the music would dynamically tie in to both the actions of the player and sound effects caused by nearby game objects, and feel as if it were "unfolding in real time".[28] Johnson felt having short pieces of music that looped without reacting to the player would be a "missed opportunity", and wanted to create music that changed while still containing a composed emotional arc. Jenova Chen met with Wintory at the start of the game's development to describe his vision for the project, and Wintory left the meeting and composed and recorded the main cello theme for the soundtrack that night. He continued to work on the soundtrack for the next three years, experimenting and discarding many ideas.[29] The game's orchestrations were performed by the Skopje Radio Symphonic Orchestra (Makedonskiot filmski orkestar "F.A.M.E.S.") in Macedonia.[30]
A serious dilemma presented itself as a result of this newfound devotion to the ancient sages because of the apparent conflict between pagan classicism and Christian doctrine. It became a matter of deepest concern for all Renaissance thinkers to find an accommodation of the two doctrines — the philosophy of Plato and the teachings of Christ. As a result of their dual allegiance, we get the term which describes the movement, "Christian humanism." The successful adaptation of double devotion is seldom better illustrated than in the works of Thomas More, especially in Utopia.
In each level, the player may come across one other player temporarily connected to their game. When players approach each other they charge one another's scarves. They cannot communicate with each other beyond patterns of singing. Players can help each other by activating strips of cloth or showing paths, but cannot hinder each other and are not necessary for completing any level.[2] When two players finish a section at the same time they remain together into the next one; otherwise, they are connected to new players when they move on. While all of the figures generally look the same, without distinguishing characteristics, individual players can be told apart by unique symbols which are shown floating in the air when they sing and are displayed on their robes at all times.[5] The entire game takes about two to three hours to complete.[2]

The name Raphael, though, may have been chosen by More to remind his readers of the archangel Raphael who is mentioned in the Book of Tobit (3:17; 5:4, 16; 6:11, 14, 16, 18; also in chs. 7, 8, 9, 11, 12). In that book the angel guides Tobias and later cures his father of his blindness. While Hythlodaeus may suggest his words are not to be trusted, Raphael meaning (in Hebrew) "God has healed" suggests that Raphael may be opening the eyes of the reader to what is true. The suggestion that More may have agreed with the views of Raphael is given weight by the way he dressed; with "his cloak... hanging carelessly about him"; a style which Roger Ascham reports that More himself was wont to adopt. Furthermore, more recent criticism has questioned the reliability of both Gile's annotations and the character of "More" in the text itself. Claims that the book only subverts Utopia and Hythlodaeus are possibly oversimplistic.
