Evaluation
OPUS: Echo of Starsong launched on August 31, 2021 and received a series of post-launch updates, culminating in the Full Bloom Edition — an upgraded version of the game that added full Japanese and Chinese Mandarin voice acting, released on May 19, 2022. The store page explicitly describes this as "the definitive edition of the visual novel-style adventure game," confirming it as the complete, final form of the title.
Post-launch content included several feature and quality-of-life patches (trading cards, cloud save, controller vibration), as well as a suite of supplementary DLC: the original soundtrack, artbook, complete soundtrack volumes, official game scripts, and an arrangements album (released March 13, 2023). All seven DLC items are released with no unreleased entries remaining.
By early 2023, SIGONO had shifted focus toward their next title, OPUS: Prism Peak, announcing it in January 2023 and promoting it in subsequent posts through August 2023. The last substantive update to Echo of Starsong was a feature patch on May 30, 2023 (adding controller vibration), and the last DLC release was the arrangements album on March 13, 2023. No new content has been announced for Echo of Starsong since then, and the developer's communications have focused entirely on the follow-up game. The game shipped as a complete narrative experience and all planned content additions have been delivered.
Evidence

About this game
OPUS: Echo of Starsong - Full Bloom Edition is the definitive edition of the visual novel-style adventure game, now with all-new voice acting. Dive in and enjoy an intergalactic journey that transcends time through love.
Echo of Starsong is a visual novel style adventure game. Asteroids emitting a sound known as "Starsongs" have become the center of conflict for the immense power they hold. Determined to claim asteroids of his own, a young man ventures out with a girl who can imitate starsongs, lending her voice to unravel an ancient myth deep in the heart of space.
"I will claim the starsongs, and bring honor to the clan."
Exiled by his people, Jun ventures out in search of starsongs to redeem himself. But progress is slow, until he saves Eda, a witch who can pick up on the sound of asteroids. However, what appears to be a blessed encounter, will end up becoming a lifelong burden...
The female protagonist - Eda, can hear the thunderous sound of starsongs in space, and navigate their spaceship towards the asteroid it came from.
The male protagonist - Jun, can explore asteroids to locate the starsong's source, which reside in magnificent temples deep within the asteroids, hiding their ancient secrets.
Throughout their journey, the crew will encounter people of all sorts. From starsong intel brokers, to asteroid excavation enforcement officers. Some may act as an obstacle, while others will prove themselves to be allies.
Most people of Thousand Peaks have a personal story to tell when it comes to the conflicts that have ravaged their homeland. Uncover the troubled history of this solar system as you get to know each character.
The story's main setting, Thousand Peaks, has been in a state of chaos ever since the war. Help the crew travel through the territories of different factions, as they gather intel on the fabled starsongs.
Echo of Starsong is a narrative-driven game. Although light puzzles and resource management are involved throughout the story, gameplay is kept simple to provide an accessible experience.
