One Hour One Life

Players gather in a village. To the right are two babies, who must be cared for by others.

Players spawn randomly into the world either as a child, with another player as mother, or as a young adult, an Eve, if the number of babies is already too high. Each minute played represents one year in the life of the player's character. For their first three years, players are unable to interact with objects and rely entirely on other players to feed them, while initially only being able to speak one letter at a time.[4] Each player has a food bar, whose size varies with age, that fills until full adulthood (17/18) and depletes over time when a player hits 40 years old. Players die of old age upon becoming 60 years old, but can also be killed by animals, other players, or their food bar being emptied. One Hour One Life is a permadeath game,[4] meaning that a player restarts from nothing after dying.

One Hour One Life has over 3000 human-makeable objects,[1] which may be produced through crafting. The process of crafting involves clicking an object to pick it up, then clicking on another object in an effort to combine them. Crafting is necessary as the food sources available without it are limited.[5]

Players have an equal chance of spawning either as a man or as a woman, which the only difference being that women alone can birth new players when they are between the ages of 14 and 39.[5] The importance of women in the survival of a tribe often leads to male children being disfavored if there is a lack of food. However, playing as a male character may be easier due to a lower chance of causing another player's death.[3]

Rohrer has said that the idea that led to the game was a thought experiment about how long it would take for humanity to get "from arrowheads to iPhones" with "the knowledge we have today". In an interview in Destructoid, Rohrer discussed the problems with building a society in the game Rust, and how he planned to remedy those issues in One Hour One Life. He argued that the occurrence of trolling and the lack of impact of death are detrimental to creating a system of justice and, by extension, building a community. In One Hour One Life, the permadeath mechanic and the initial period of helplessness when a player spawns as a baby serve to force people to work together. Rohrer also commented that the themes of death and the choices made in the face of death are "constant in [his] career" and saw One Hour One Life as bringing together the ideas found in his other games into a "cohesive whole".[6]

An important part of the game is the idea of sustainability, which Rohrer discussed by email with Matthew Gault, writing in Vice Motherboard. Because villages run a risk of overexploiting their surroundings, successful communities require good resource management. Rohrer describes this as necessitated by the game's high difficulty, which is reinforced by repeated failure: all villages will die eventually, but the societies supporting cooperation and sustainability are able to survive longer. Over time, players have become better at continuing family lines, which Rohrer attributes to the emergence of culture, morality and taboos supporting these ideas. This is connected to Rohrer's own belief that morality does not exist as an independent concept but has evolved for practical reasons.[7]

After the game's release, Rohrer stated that the game had been in development for three years and that he had at least two more years of work left.[8] During this time he aims to create craftable objects until the game has 10 000 of them. To accomplish this, Rohrer created a program that automatically traces sprites from scanned images.[6] If required, he records a crafting sound for the object with his own voice.[9]

One Hour One Life was released on 27 February 2018 on the website onehouronelife.com. In an interview with Richard Moss in Gamasutra in August 2018, Rohrer described that he deliberately had avoided putting the game on digital distribution platforms such as Steam and GOG. His reasons for doing so included the large amount of work needed to integrate the game's code into these services, as well as the control offered by hosting the game independently, which he described as allowing "a very sort of customized experience" in regards to "how the website [...] is sort of integrated with your account". The game's website, aside from distributing the game, contains various information about things such as family trees and character trivia. Rohrer describes this as giving the website the feel of a "cohesive portal" for the game.[10] The game was released on Steam on 8 November 2018.

KG Orphanides, in an article in Wired, described the game as tough but more accessible than Rohrer's other games, while noting the game's short sessions allowed for casual play. Orphanides also praised the game's social aspects and found the game successful in condensing human life within its short time span.[3]

Matthew Gault, writing in Vice Motherboard, described the game as having "broke[n] [his] heart and restored [his] faith in humanity". Gault went on to say that while the survival gameplay is reminiscent of Don't Starve, One Hour One Life also touches on themes of "sustainability, morality, and civilization". He also stated that despite the hostile nature often found in game communities the players of One Hour One Life generally take care of each other.[7]

Roberto Turrini, reviewing for the Italian game magazine The Games Machine, called One Hour One Life a "masterpiece of game design" and claimed it lacked any negative aspects. He rated the game 9/10.[11]

One Hour One Life had poor sales figures at its Steam launch, selling 315 copies compared to 2400 for Rohrer's The Castle Doctrine. However, sales improved over time.[12] Four months after the launch on Steam One Hour One Life had grossed almost $700,000.[13]

Developer Dual Decade runs an unofficial mobile fork of the game, titled You Are Hope, for iOS[14] and Android.[15] It uses a fork of the One Hour One Life source code but runs on an independent server hosted by Dual Decade, and features a number of changes and additions. Only the chinese version has ads.

Jordan Thompson, writing for TouchArcade, rated the game 4 out of 5 stars in a review, describing it as a "more mechanically deep version of Don't Starve" and praising the player interaction and the decisions of life-and-death "that will sit with you long after you play". Maria Alexander reviewed the game for Gamezebo, giving it 4.5 out of 5 stars while saying that it was "a crafter's dream" due to the many ways in which materials can be broken down and used. Both reviews criticized the mobile controls, though Gamezebo considered it only a minor issue.[4][16]
