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 20 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.
About
“The Book of Hiro” is a 3D visual puzzle game developed by two independent developers. Players help Hero embark on an adventure to the palace, using illusions and perspective to solve puzzles and explore the magical world in this book.
The game features innovative visual puzzles that are imaginative and visually stunning. The innovative visual illusion finding gameplay involves moving the viewing angle, clicking, and other operations to find the hidden “key” pattern in the picture. Each puzzle solved can advance the plot and provide a unique gaming experience and visual impact.
The game features a simple and fresh 3D low-poly style that is full of childlike innocence while meticulously depicting the different scenes in the story. The game’s soothing and distant music complements the graphics to create a mysterious visual pop-up book.
The game features shiny gold coins, ordinary keys, hammers, gears, and other objects that are common but difficult to find due to the game’s unusual mechanics. Players must make bold guesses and not be fooled by seemingly unrelated images. They must carefully observe and remember that what they see is not necessarily what they get!
The game features an energetic and art-inspired storybook style. Behind the seemingly ordinary protagonist’s travel story is a hidden plot and an extraordinary experience. The game includes a main storyline and hidden endings waiting for you to explore.

创意不错但是好短啊,感觉没怎么弄就结束了。
nice
感觉画风挺可爱的,游玩方式也很新奇,寻找的时候旁白会有提示,而且如果卡关太久,也会有自动对准,不过是免费的,所以内容有点少,二人制作的小游戏还能有隐藏结局已经挺不错的了,还是很期待会有序章发行,期待后续能有什么样的故事

画风很好。解密有点偏向无厘头了。虽然有提示,但是20%的情况下是提示了也没看出来图案在哪里。成就很简单。双结局。打两遍用时90分钟。第二遍,20分钟就可以全部通关了。不是一个耐玩的游戏。7折入的。
谜题很考验想象力,充满了跳跃的思维,如果和作者对上了电波就会恍然大悟。隐藏结局的钥匙,当作者回应我的直觉时真的很爽!画面氛围很棒,无论是色彩还是表现力都很出色。如果一些物品(例如坍塌的地牢中开门的机关)在造型上能更贴近直觉,玩起来会更舒服。一些核心的交互点可以做一些视觉引导,以便让玩家把精力集中在寻找形状这一核心玩法上。背景音乐好听,如果开箱子、移动机关等交互可以加上音效,整体的音频表现可能会更加丰富、生动。游戏玩法很有创意,体验过程充满惊喜,期待下一部作品!

The Book Of Hiro is a puzzle game, in which each chapter consists of a small but detailed 3D diorama. To progress to the next chapter, a scroll containing a 2D sketch must be found and placed on the matching part of the scene (after changing the viewpoint to align shapes, markings etc - this can be very challenging, even in the small scenes). The matching 3D object is then created e.g. a cog, key, hammer etc, which in turn can be used to reveal further scrolls, or finally to open the route to the next chapter. There are achievements for completing each chapter and for obtaining the default ending. The story has a voiced narration and is also shown in displayed text; the narration is always in Chinese (which I thought was a nice, almost musical, accompaniment to the story, even though I do not speak that language). A hint is given by the story-teller if the player seems to be stuck, and there is also a "?" button which will show the correct alignment for matching the sketch on a scroll (though the player still needs to place the scroll). There are also arrows for moving backwards or forwards to any chapter previously unlocked; these are not needed for the default ending [spoiler]but are crucial for the alternative ending and its associated achievements.[/spoiler] I originally played the Prologue for this game almost two years ago, and I struggled with the mechanics so I did not purchase the full game until now. This time I found that I better appreciated the care and complexity of the full game's design [spoiler](including the back and forth between chapters to pursue the alternative ending),[/spoiler] and felt more comfortable with the mechanics - the alignment of the viewpoint can be tricky but the game does allow & automatically corrects a certain tolerance of error. All in all I am very glad that I played the full game; it was both challenging and entertaining, and very good value for money.
晕3D和眼神不好的人一定要慎重再慎重,很多时候找不到零件会很坐牢,虽然你过不去它会给你提醒,但接受了提醒游戏体验也会下降,只能说是一个还算有新意的视觉游戏。
虽然很短,不过游戏模式很不错,赶快出DLC!
是一个考验耐心观察力和脑洞的小品游戏,轻松愉悦,过年的时候几个小时无聊正好解闷儿。个别物品不好找,不仅是其他东西干扰,也很随缘看当时玩家的视角角度,可能要找好久,可能不小心就会发现23333,再加上系统判定吃角度,所以有时候挺急人的。。。 有隐藏物品,着急速通的可以去搜视频教程,纯为了自己休闲的我还是建议先第一遍正常玩第二遍再全成就,不然挺累的,打折入的价格也没必要2小时卡bug [spoiler] 二周目看了b站去解锁隐藏成就,结果不小心把普通结局那块砖又贴上去了!!后悔死了!!不能后退!!导致重玩第三遍,哭晕,大家一定小心啊啊啊啊啊(隐藏结局贴砖那个地图直接贴特殊砖就行,不用再走一遍普通寻物了)[/spoiler]大年初二,大家春节快乐!!
