Jinsei Owata no Daibōken (Japanese: 人生オワタの大冒険, lit. "The Great Adventure of 'My Life Is Over'") is a Japanese browser-based platform game developed by the independent creator King and released for free online as an Adobe Flash game in the late 2000s.[1][2] The game features the 2channel (2ch) ASCII-art character Jinsei Owata (人生ｵﾜﾀ \(^o^)/) as its protagonist and became known for dense "trial-and-error" level design with numerous instant-death traps.[3]

A sequel, Jinsei Owata no Daibōken 2 (人生ｵﾜﾀの大冒険2), was released on 15 August 2020, shortly before Adobe Flash Player support ended in late 2020.[4][5] Following the end of Flash support, the games were later made playable again via the open-source Flash emulator Ruffle and were re-published on King's website in November 2023.[6][7]

Gameplay

Jinsei Owata no Daibōken is a side-scrolling platform game in which the player controls Jinsei Owata—commonly represented by the emoticon "\(^o^)/"—through stages constructed largely from ASCII art, with the goal of reaching the end while avoiding traps that typically kill the character in a single hit.[3][1] The player's basic actions are movement, jumping, and firing a forward projectile (the "Owata Buster").[1] Frequent deaths are expected, and the game encourages repeated attempts via fast restarts (a retry function).[1]

The sequel retains the same core controls and structure while thematically framing its setting around the impending end of Flash content; contemporary coverage described the sequel as taking place in a disappearing world tied to the shutdown of Flash support.[8]

Development and release

According to interviews with King published in Japanese media, the project originated from King's familiarity with 2channel ASCII-art culture and the Jinsei Owata character, and he began developing the game while a university student as part of learning and practicing Flash development.[9] Version logs archived by the Flashpoint preservation project list early public releases in January 2007 and subsequent updates during 2007.[2]

Japanese coverage in 2010 reported that the game was released as a "complete version" in September 2009, and that it later included additional stages referencing I Wanna Be the Guy (IWBTG).[10]

Jinsei Owata no Daibōken 2

On 15 August 2020, King released Jinsei Owata no Daibōken 2 for free on his website, with multiple outlets highlighting its release as one of the last notable new Flash games before the end of Flash support.[4][3][5] The sequel was widely framed as explicitly referencing Flash's impending discontinuation, including in feature coverage by Denfaminicogamer.[8]

Removal and re-release via Ruffle

After Flash Player support ended at the end of 2020, playing Flash games in modern browsers became difficult without emulation.[7] On 19 November 2023, Japanese outlet AUTOMATON reported that King re-published Jinsei Owata no Daibōken and its sequel on his website using the open-source Flash emulator Ruffle, making the games playable again in a browser environment.[6] Denfaminicogamer similarly noted that the re-release relied on Ruffle for browser playback.[7]

Reception

The series became known in Japanese internet culture for its extreme difficulty and frequent "instant-death" surprises, and it is often discussed as a representative example of Flash-era "die-and-retry" action games.[3][5]

In 2020, the Suntory coffee brand Craft Boss released a promotional web video reflecting on the history of Flash culture; contemporary reporting noted that the video referenced multiple Flash-era internet icons, including Jinsei Owata.[11][12]

Legacy and influence

Japanese outlet GetNews reported in 2010 that Michael "Kayin" O'Reilly, creator of I Wanna Be the Guy, sent a message to King thanking him and stating that O'Reilly had been inspired by Jinsei Owata no Daibōken.[10] Denfaminicogamer's 2020 feature on the sequel also discussed the game's ongoing influence and noted continued interest in the series around the end of the Flash era.[8]

The game has also been referenced in academic writing discussing Flash-era online game culture; a 2022 article on Flash and online media history cited King's Jinsei Owata no Daibōken (2007) among notable Flash works and provided the official URL.[13]
