The complete OPUS experience awaits here 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 narrative puzzle 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 magnificant 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.
Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
Charts
Each storefront's own chart, in its own country — the closest public signal to sales where none is published. A country missing from a list is one we don't collect there, not one where the game doesn't chart.
Same day: best CN #228, worst US #263 · 7 markets collected
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
For scale, across GOG · Trending · United States over the last 30 days: the 141 chart moves that followed a price cut of more than 20% went a median of 2 places away from #1, and the 6,557 moves with no price cut behind them went nowhere. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Stats
How fast this game is gaining ratings — the activity signal available where a store publishes no sales or install numbers.
Measured from our own daily snapshots, not reported by the store. Deliberately not converted into sales: a one-tap rating's ratio to copies sold is unknown on this platform, and guessing it would be worse than leaving it out.
Sums Steam only; GOG, Xbox, PlayStation, Epic publish no volume signal, so the true total is higher by an unknown amount.
