{{nihongo|Touhou Gouyoku Ibun ~ Sunken Fossil World|東方剛欲異聞 ~ 水没した沈愁地獄||{{lit.}} "Strange Tale of Avarice ~ Submerged Hell of Sunken Sorrow"|lead=yes}} is a shoot ‘em up platformer game developed by Team Shanghai Alice and Twilight Frontier numbered as the 17.5th game of the Touhou Project series. Sunken Fossil World was fully released on October 22, 2022, featuring new playable characters with its semi-full release on October 24, 2021 at Autumn Reitaisai 9 after two demo releases prior on October 6, 2019, and October 18, 2020. On the official website, it is described as a "horizontal side-scrolling danmaku water action game".{{Cite web |title=東方剛欲異聞 ~ 水没した沈愁地獄 |url=https://tasofro.net/touhou175/index.html |website=Tasofro}} It consists entirely of boss fights unlike the pre-boss and boss fight stage structure found from most Touhou Project games.

Gameplay

Sunken Fossil World involves bullet hell gameplay containing a boss rush style where continual boss fights of set number occur with dialogue between two characters preceding each boss fight and, during each one, there being platforms which differ depending on the boss fight.

Development

Like all previous Touhou Project spinoffs where Twilight Frontier was involved, ZUN, or Team Shanghai Alice, only oversaw the development of Sunken Fossil World while Twilight Frontier actually developed the game.

Compared to other Touhou Project games, Sunken Fossil World’s development occurred with more intervals, divided into a first trial demo, a second trial demo, and a full release after three delays. Sunken Fossil World’s first trial demo was released on October 6, 2019, showcasing only three different boss fights. Sunken Fossil World’s second trial demo was released on October 18, 2020, which significantly added more material including a final boss for all the playable characters at the time. Sunken Fossil World was set to fully release at Reitaisai 18 on March 21, 2021, but it was announced that Sunken Fossil World would be further delayed due to parts of the game still not yet being developed and a last-minute attempt being disregarded, as this was said would lead to “omission of the contents” and “would leave some concerns about the development and that it would take time to update the game in response after release”.{{Cite web|url=https://twilightnewspaper.wordpress.com/2021/03/15/touhou-17-5-touhou-gouyoku-ibun-delayed-and-will-not-be-released-and-distributed-at-reitaisai-18/|title=Touhou 17.5 "Touhou Gouyoku Ibun" delayed and will not be released and distributed at Reitaisai 18|date=15 March 2021|access-date=15 November 2021}} It was then set for an August release, but this too was delayed to September and then October.{{Cite web|url=https://twitter.com/tasofro/status/1432278260688195587|title=Due to circumstances, Touhou Gouyoku Ibun, which was set to release during August, will be readjusted to a September release on Steam. We would appreciate your patience.|access-date=24 November 2021|language=Japanese|date=30 August 2021}} Because of delays, the game presents a subtitle of "17.5", despite being released after the 18th Touhou game, Unconnected Marketeers.{{Citation needed|date=March 2025|reason=I believe it was always called “Touhou 17.5,” yet if I am wrong, and either way, please provide a source.}}

The game was released at the Autumn Reitaisai 9 on October 24, 2021, and released on Steam on October 29, 2021. The game was updated to Ver 1.02 on November 2, 2021, shortly after its release with a bug patch.{{Cite web|url=http://tasofro.net/arc/index.html|title=Twilight-Frontier|access-date=15 November 2021}}

A Nintendo Switch port as well as an update featuring new playable characters and storylines was announced in May 2022.{{Cite web |last=Romano |first=Sal |date=2022-05-02 |title=Touhou Gouyoku Ibun: Suibotsushita Chinshuu Jigoku coming to Switch this fall in Japan |url=https://www.gematsu.com/2022/05/touhou-gouyoku-ibun-suibotsushita-chinshuu-jigoku-coming-to-switch-this-fall-in-japan |access-date=2022-05-02 |website=Gematsu |language=en-US}} This was released on October 20, 2022, and also added English and Chinese language support to both versions of the game.
