The Big Adventure of Owata's Life (人生ｵﾜﾀの大冒険, Jinsei Owata no Daibouken)¹⁾ was a series of AA threads around 2006²⁾ that focused on Owata's attempts at heading into Jukai,³⁾ but he dies and explodes in a Mega Man-like fashion,⁴⁾ which stops further progress.

However, this name has mostly been associated with the Flash game that was developed by “King” (キング ◆KING75wl/Q) during the late 2000s, famously serving as the main inspiration for popular trial-and-error games, namely I Wanna Be The Guy and Shobon no Action.

The game is very easy to understand and doesn't have a lot of dialogue. It features Owata navigating through a total of four routes, depending on the direction they head in, and facing a total of 5–6 bosses. At the end of each route, there is a 'reward' for the player, similar to defeating a Mega Man stage, but the two main 'endings' of the game are only in the routes that are horizontal to the first room, as the story normally goes.

In 2006, “King” was a college student who liked AA threads on 2channel and Flash games, so he went on to develop an AA-themed Flash game during Winter Break.⁵⁾ The first version released on January 1, 2007,⁶⁾ with the starting screen and Kuma fight,⁷⁾⁸⁾ and eventually,⁹⁾ tanasinn was added as a boss in the first batch of updates.¹⁰⁾¹¹⁾ While the game spread, development paused after February 12, 2007.

This early version would famously inspire “Kayin” to develop and release I Wanna Be The Guy on October 7, 2007,¹²⁾ which gave “King” the motivation to complete Jinsei Owata no Daibouken. As such, the 'full' version released on September 20, 2009,¹³⁾ including a direct tribute to I Wanna Be The Guy in one of the new routes, then Gadget News broke the news that “Kayin” and “King” congratulated one another over email.¹⁴⁾

In the past, Jinsei Owata no Daibouken used to have a changelog, but the link was removed and it stopped updating after the v1.07 update on February 25, 2011. Despite its age, Jinsei Owata no Daibouken quietly received updates since 2019 after the news about the end of Flash gained traction, then Ruffle compatibility was eventually added on November 19, 2023.

Jinsei Owata no Daibouken 2 (人生オワタの大冒険2), or Owata 2, is a sequel that was developed by “King” and published on August 15, 2020^15)16)17)18) with “Asagen” handling the new music.¹⁹⁾²⁰⁾ Considering the circumstances, the game was a 'love letter' to the AA and Flash era as the end of Flash was looming, so it was comparatively easier as a way to let players beat the game within the final five months.

Unlike the original game, Jinsei Owata no Daibouken 2 has a story where Owata faces said existential threat with the AA world 'disintegrating' as Flash's scheduled end comes on December 30, 2020. The game has a total of 15 maps and 2 bosses that players can resume from at any time. The mid-boss is Yaruo and Yaranaio, while the final boss is an Undertale-style²¹⁾ battle with Mona and everyone else.

• Before Tanasinn was added, the room before had an 'Under Construction' (工事中, Kōji-chū) sign.²²⁾
• In the past, 'Easy Mode' was initially called 'Yutori Mode' (ゆとりモード, lit. “Relaxed Mode”),²³⁾ but the modes were later changed to 'Easy' and 'Hard' as the reference would be lost to time.
• Owata has four poses in total: the 'Owata' pose (O), the 'what the hell' pose (N),²⁴⁾ the 'Fuji-san' pose (F), and the 'cool' dabbing pose with a 'clink' or 'shakīn' (シャキーン) noise (S).
