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.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 14 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. 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.

What a gem! It is not a long game but each second was enjoyable. The music is amazing, and the visual aspect is so different to other games but still impressive. The story was compelling and you feel and suffer with the protagonist along their ride. The camera can be a bit tricky sometimes but gameplay was fun enough, with skills being unlocked and lots to discover. It reminded me a lot of games such as Spirit of the North or even ICO. If you tried those ones and liked them, do not miss this one. Now I need to find the OST, such a beauty.
Rarely ever write reviews but felt this warranted one. This game was beautiful and had me all in my feels. Game shifts from charming to sad to haunting. Puzzles are well done and the art direction for the game is really unique. It's a short but sweet experience. I finished at 6.6 hours, but it's one of those games that just grabbed me.

看画风直接买了,进去之后漫无目的XJB乱逛找了十几分钟道具,开始熟悉的晕3D想吐了...... 我就知道这种风格太容易3D眩晕了,但就是忍不住尝试......
I finished up my playthrough on stream today and absolutely loved the experience. The art style of a purely particle based world is very unique and I can see it being hit and miss with people because of this. Personally I loved it, the style and art direction really made the game stand out. The music was also top notch and really fit the world and presentation of the game. The story flowed well and the pace of the game felt right. It is told through audio visual clues with optional notes you found which led to an ending that for once I didn't see coming. This is a really good first project from a new indie developer. I had no bugs or problems with the game, only minor thing I can say about the game is I wish there were more options, especially audio options for the game (which I have passed onto them as feedback). To quote their web site: "We aspire to create thought provoking game worlds filled with wonder and discovery, with imaginative visuals unique to the medium." To Underwater Fire Games, you really delivered on this quote and I look forward to seeing what future projects your small team comes up with.
A beautiful game that feels new yet nostalgic at the same time. It touches on some heavy topics but in an accessible way that my 5 year old son was able to still enjoy while watching me play. It touches on themes of loss, regret, consequences and fate. It is very heartfelt and the music is amazing. Tonally it lands somewhere between Shadow of the Colossus and Breath of the Wild with an emphasis on exploration and puzzles. Quite an achievement for such a small team. I highly recommend it.
A SUPER good game made only by four people. The gameplay, music, and art are all really impressive.
This game is stunning. You can tell a lot of love went into it. A team of 3 pouring their heart into something beautiful!
I m loving this game already.. it's amazing 😍
芸術を味わいたくて買ってみましたが、キーマウユーザーに優しくないので返品しました。 視点スピード調整ができないので、マウスを少し動かしただけで首がねじ切れるほど振り返る。 自分のしっぽを追いかける犬みたいに視点がグルグルします。 しかも私が苦手な、自分の移動につれてゲーム側が勝手に視点を調整するタイプ。 スタートから数分試しただけで激しく3D酔いしたので諦めました。
A very gorgeous game that really shows that particle effects can be used for a lot more than just making combat look more exciting. The game is really good at implying the mystery of things early on, and the puzzles are a good means of teaching more about the mechanics and how they can interact. The music is also good enough that I hope the soundtrack goes up for sale at some point. I expect to come back later to go after any wind chimes I miss in my first playthrough.
