No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $167.4K — a different platform, not this one.
Memories linger across time, deep beneath the island’s surface... In this story-driven 3D platformer, explore Sephonie Island's massive cave network, and link with unidentified species using the novel Puzzle Grid system. Explore the island's depths as shipwrecked biologists Amy, Ing-wen, and Riyou, whose personal histories come to bear on the shifting spiritual landscape of the island depths. Parkour-esque platforming Use an acrobatic moveset to navigate lush, jade canopies and rusty sandstone spires. Fling yourself over high ledges using the satisfying Teledash Vault and deftly Wallrun across dangerous outcroppings. Grapple through the air with the help of long-tongued Ribbats or climb tall cliffs via sticky-ridged Gripshrooms. Linking with certain creatures will grant you new abilities to reach the farthest depths of the island. The Relaxing and Casual Puzzle Grid System The trio must research the island's unknown creatures by Linking with them. Using the one-of-a-kind "Puzzle Grid" system, you'll rotate and place a series of multi-colored pieces onto the board to create large, same-colored islands. Each creature has different challenges to overcome! There's no 'right' solution to Linking: use your intuition to react to the creature's moves and what appears on the board, and you will soon be on your way to success! A Research Trip Gone Awry In the near future, three biologists are on a joint mission to use their state-of-the-art ONYX implants to research the creatures of the uninhabited Sephonie Island. But as they approach the island, a sudden storm leaves them shipwrecked. Amy Lim, Taiwanese-American and bold leader, hails from the midwestern USA town of Bloomington. Riyou Hayashi, an analytically-minded Japanese-Taiwanese researcher, calls the bustling Tokyo his home. And Ing-wen Lin, a kind and considerate Taiwanese scientist, lives in Taipei. The trio will find their motivations and loyalties put to the test as they navigate Sephonie’s caverns, facing not only physical challenges but also their deepest memories and dreams. As they grow more intimate with each other and the island, an ancient force, brewing deep in the island's abyss, may threaten their newfound relationship, and the world... Features A deep, emotional story about the close bonds of a trio, the priorities of nations, and the delicate connection of humans and nature. A human experience crafted entirely by the IGF Grand Prize-nominated duo of Marina Kittaka and Melos Han-Tani, behind works such as Anodyne 1 & 2, Even the Ocean, and All Our Asias. Master a parkour-esque moveset to sprint, wallrun, jump, and fling yourself through Sephonie Island’s rocky and physical caverns! A novel and accessible Puzzle Grid system that will stretch your brain in fun ways. A screenshot mode that lets you pose the characters and creatures you meet in the game, and then take fun photos! A beautiful and varied cave system filled with all manner of large and surprising creatures, visually brought to life by Marina Kittaka. A lush, melodic and ambient soundtrack by Melos Han-Tani. The postgame “Bubble Adventure” and fiendish hidden items provide a fun challenge for advanced spelunkers. --- Sephonie does not support square resolutions (Less wide than 16:10). Sephonie will run fine with these resolutions but some UI may be cut off, which you can fix by using the in-game UI Scaling option or by running the game in a 16:9/16:10 windowed resolution. The same goes for UWHD resolutions in fullscreen. Sephonie only officially and natively supports certain controllers (PS4/5, XB1/XB360). Other controllers may work, but functionality is not guaranteed. In particular the Nintendo Switch Pro Controller is NOT supported although players have gotten it working.
Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
10 of 15 markets; the rest we haven't asked for this title, not markets where it is unavailable.
Availability
We put this game to every storefront we collect. A market that answered not sold has told us something about the game; a market we never asked has not, and the two are never drawn the same.
10 on sale4 answered “not sold”1 we did not ask
The 4 “not sold” markets are read from the GOG price pass of Sep 4: that day the store answered for this game elsewhere and gave no price in those. The 10 priced markets are the same rows as the table above — each the latest price we hold, dated here when it is older than that pass. The 1 marked “not asked” were not put to this store at all — either it has no storefront there or we do not collect it yet, and neither is a statement about the game. A refusal is a refusal on one day; a store can list a title again tomorrow.
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, PlayStation, Nintendo publish no volume signal, so the true total is higher by an unknown amount.
