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". 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. The game's orchestrations were performed by the Skopje Radio Symphonic Orchestra (Makedonskiot filmski orkestar "F.A.M.E.S.") in Macedonia.

The few criticisms for the game centered on its length and pacing. Clements noted that not all players would appreciate a game with a "deliberate, melancholic pace" and short duration, comments echoed by the Edge review. Miller noted the lack of complex gameplay elements in Journey, and Shaw was disappointed that the game was only a few hours long, though Douglas said the length was perfect. Miller concluded the game could be compared to "a musical concert, a well-directed film, or a long-awaited book", while Clements concluded, "completing Journey will create memories that last for years".
Every individual is employed according to his classification — in an office, a factory, a hatchery, on a farm, or flying a helicopter taxi. A great variety of entertainment is provided for after-working hours — sports like electromagnetic golf, Riemann-surface tennis, and centrifugal bumble-puppy. There are lively nightclubs and "feelies," movies that provide accompanying scents and that also stimulate appropriate tactile sensations. Every evening seems to end with going to bed with someone of the opposite sex. Sexual relations are completely promiscuous. "Everyone belongs to everyone" is one of the clichés drummed into the consciousness through conditioning. There is no such thing as a marriage. Contraceptives are provided by the government to make sure that people will not interfere with the test tube method of producing children. Sex is purely for sport.
The multiplayer component of Journey was designed to facilitate cooperation between players without forcing it, and without allowing competition. It is intended to allow the players to feel a connection to other people through exploring with them, rather than talking to them or fighting them. The plan was "to create a game where people felt they are connected with each other, to show the positive side of humanity in them". The developers felt the focus on caring about the other player would be diluted by too many game elements, such as additional goals or tasks, as players would focus on those and "ignore" the other player. They also felt having text or voice communication between players or showing usernames would allow players' biases and preconceptions to come between them and the other player.
