A short, free adventure from a Japanese developer, five days with a half-broken android girl.
Per its Steam store page, ECHOES is a short adventure in which a young man wakes in an unfamiliar ruin in a world that has ended and spends 5 days with a half-broken android girl. A very simple puzzle of deciphering her broken words and their sounds sits at its center, and how you proceed splits the story into 3 endings; the developer estimates 0.5 to 1 hour of play. The maker is Bigo, listed as both developer and publisher on Steam. No text directly stating nationality was found; Japanese development rests on the Steam listing (Japanese is the only supported language), the developer's own Japanese-language post on X announcing the store page, and Denfaminico Gamer calling the maker an individual developer. It was released on July 31, 2026, is free and not in Early Access; the soundtrack is a paid DLC at 265 yen. It is Very Positive with 106 of 107 reviews positive, about 99 percent; 92 are Japanese and 3 English. Steam supports Japanese only. Steam's content descriptor ID is 5 (General Mature Content): the developer notes violence and death in text only, with no blood or gore in the art or animation. There is no AI disclosure. AUTOMATON Japan, Game*Spark, Denfaminico Gamer and Gamer have run announcements or introductions, so it is not undiscovered in Japan, but it has barely reached English speakers.

01First, the one feeling
- The story takes place across 5 days with one broken android girl, so the whole game is the length of a single relationship, and the short running time is part of the design rather than a shortage.
- Her words are broken and you decipher them and their sounds with a simple puzzle, so understanding her is something you do with your hands, and being able to read her words becomes the same act as getting closer to her.
- How you proceed splits the story into 3 endings, so the 5 days are not only watched but shaped, and the choice of how to treat a half-broken companion is what the ending answers.
02Who this is for (and who it is not)
For you
- You want the taste of planetarian, a person and a robot sharing a short, quiet time in a world that has ended, in a form with a simple puzzle and 3 endings, made by an individual Japanese developer
- You want something short and free: 0.5 to 1 hour by the developer's estimate, free on Steam, with 106 of 107 reviews positive
- You want to dig up something that has barely reached English speakers: 92 of its 107 reviews are Japanese and only 3 are English
Not for you
- You need English: Steam supports Japanese only, and English is not supported
- You want a long game, or you are wary of dark themes: it runs about 0.5 to 1 hour, and Steam's content descriptor notes violence and death, and implied death, in text, though without blood or gore in the art

ECHOES Buried gem
Per its Steam store page, ECHOES is a short adventure in which a young man wakes in an unfamiliar ruin in a world that has ended and spends 5 days with a half-broken android girl. There is a very simple puzzle of deciphering her broken words and their sounds, and how you proceed splits the story into 3 endings; the developer's own estimate is 0.5 to 1 hour of play. Steam's user tags include Post-apocalyptic, Robots, Visual Novel, Story Rich and Multiple Endings. The maker is Bigo (びご), listed as both developer and publisher on Steam. No text directly stating nationality was found; Japanese development rests on the Steam listing (Japanese is the only supported language, English is not supported), on the developer's own Japanese-language post on X announcing the store page, which the store page links to, and on Denfaminico Gamer calling the maker an individual developer. The game was released on July 31, 2026, is free (Free To Play, not Early Access), and the soundtrack is a paid DLC at 265 yen. On Steam it is Very Positive: 106 of 107 reviews are positive, about 99 percent. By language, 92 are Japanese, 7 Simplified Chinese, 3 English, 2 Traditional Chinese, 0 Korean and 3 other, so Japanese is by far the largest. Steam's content descriptor ID is 5 (General Mature Content); the developer's note says it contains violence and death, and implied death, in text only, with no blood or gore in the illustrations or animation. There is no AI disclosure on Steam. This is not an undiscovered title in Japan: AUTOMATON Japan, Game*Spark, Denfaminico Gamer and Gamer have run announcements or introductions. It has barely reached English speakers, with only 3 English reviews.
Give it your first passplanetarian HD The origin
The origin of this taste: planetarian HD (Steam app 623080), a short, sad Japanese visual novel in which a traveler wandering a world ruined by war and close to ending meets a small robot and spends a short, quiet time with it until the story is over. The link to ECHOES is this site's own reading, not a claim by the developer: no record was found of the developer naming planetarian, and neither the developer nor any source is cited as saying ECHOES was influenced by it or pays homage to it. What carries over is the situation: a person and a robot, in a world that has ended, sharing a brief and quiet stretch of time. Where they differ: planetarian has no branching choices, while ECHOES has a very simple puzzle of deciphering the android girl's broken words and their sounds, and how you proceed splits it into 3 endings; ECHOES is also free, runs about 0.5 to 1 hour by the developer's estimate, and supports Japanese only.
