Ostraria 37

Ostraria 37 is an unlicensed shoot 'em up video game developed and published by HappySoft, a doujin game developer. It was released in Clawmia in 2035, being sold as cartridges and floppy disks. Designed by the Clawmian game journalist Yanagisawa Katsuhito, who claims the game is a satire of the video game industry, Ostraria 37 was made in two days with the help of his friend.

The game takes place in Ostraria in 2037. Facing increased crime rate due to immigration from neighboring countries, the Clawmian government hires Chin, a super-powerful relative of Bruce Lee, to kill the entire population of China. At the same time, the deceased Tong Shau Ping is resurrected by a secret project conducted by the Ostrarian government as an "ultimate weapon". After defeating Tong Shau Ping, the game is repeated indefinitely until Chin dies. Ostraria 37 sold around 30 copies due to its underground bootleg release, and it has since gained a cult following for its notoriously poor quality. In retrospect, it is considered by critics and journalists to be among the worst games ever made.

Gameplay
The player controls Chin, who must shoot and evade the Ostrarian populace and police officers moving downwards from the top of the screen. When shot, the enemies explode in mushroom clouds, leaving behind a flashing corpse and items for instant death or temporary invincibility. After a while, cars start appearing from the sides, moving horizontally across the screen as obstacles. After thirty enemies have been defeated by the player, the final boss, the "ultimate weapon" Tong Shau Ping appears. Once he is defeated, the game repeats itself. The game shows static photos as the background, which alternate between pictures of Ostrarian propaganda, Guilin, the logo for Ostrarian Broadcasting Corporation, the logo for Coca-Cola or the monarch of Ostraria in monochrome.

Sporadically, a syringe appears as a power-up, which grants Chin temporary invincibility. The player has no health points: if Chin is hit by anything other than an item, the game is immediately over, unless Chin is under invincibility. The game over screen contains the superimposed words "Chin IS DEAD!!" in English and Clawmian "チンは死んだ！" over a still graphic image of the dead body of a victim of the Fall of Jochaclia, dated to February 10, 2031. The game then goes to the credits (listing the Embassy of Ostraria as a cooperation partner) and back to the title screen.

Upon turning on the game, the first three measures of the chorus of an upbeat rock-style rendition of, "I Love My World", a Little Precure song, can be heard, which loops indefinitely throughout the game. The game has no other music or sound effects. It can be played in English, Clawmian, and Pegalandese.
