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 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

Enter a bloody loop of fate deep under the ocean. Will you become everyone’s salvation?
A train shuttling underwater carrying students and teachers on a graduation trip is suddenly trapped in a strange time loop, endlessly experiencing the moment of a derailing accident......
Our protagonist Ren and his friends are onboard a high speed rail train, which is a tourist attraction that goes through the belly of the sea. What they do not know is that once upon a time, the train is a vehicle for time travel experience.
The joyful journey quickly spirals out of control when the train derails, locking everyone in the moment of the bloody incident that endlessly repeats itself.
Ren happens to be the only person that remembers each and every fateful loop. But what’s even stranger — with each repeating loop, one more of his classmates dies before the train’s derailing moment. A mysterious murderer has appeared, and in the name of deliverance hunts down and kills Ren and his friends......
Male protagonist. He loves railroads and trains, especially the epoch-making undersea broad gauge tourist train "Time Traveler".
He has a straightforward personality and up to two friends. He has grown up with
Cecilia and Sol since childhood. No matter what happens, they would face everything together and solve them.
A childhood friend of Ren, she has a therapeutic personality. Her dream is to start a beautiful and ordinary family.
The sole heir to the Caecius Corporation. Also the inventor of the time machine during the time travel on the undersea railway.
She is beautiful and is versed in both literature and military affairs, but under the perfect appearance, there seems to be a hidden side.
There was a rumor on campus that she was conducting some kind of grisly experiment using humans.
The personal maid of Luna. Also an underclassman of Ren, Sol, and Cecilia by one year. Will do anything for Luna, even if it means sacrificing her own life. Seems to have experienced something in her life, making her expression always that of a gentle smile.
A friend of Ren and Cecilia. A star player of the school basketball team. Has a very robust build, but seemingly not too much of a ladies’ man. Always confused about the subtle relationship between Ren and Cecilia. Half of it is out of worry, and the remainder is frustrated watching over the two of them.

整体:瑕不掩瑜,算是佳作,值得一玩。 优点:立绘精美,剧情新颖,人物形象鲜明,青梅竹马确实好嗑 缺点:画面经常出现卡死,没配音,部分剧情经不起推敲,大多选项对剧情基本没啥影响,主线缺少分支,cg太少,双女主白毛没ge。
第一次看到這款遊戲是因為兔姬跟ミル的直播,看了片段後直接愛上,當下馬上就跑去找其他有遊玩的實況主把所有結局看完 個人原因導致我現在才能親自體驗這款遊戲,親自體驗過後我更愛了,我心目中的NO.1 期待小鹿老師能再度創作視覺小說

Great VN with virtually no filler make for a gripping a tightly bound story. The characters are only a small level up from being complete tropes but the focus is on their involvement in the time travel elements as well as the romance plots, so it is hardly an issue. Music, sound and visuals are also acceptable, but not the highlight. The story is obviously deeply reminiscent of Stein's Gate as many will point out but doesn't meander as much and the time travel system in Rail of Mobius is unique enough. The romance in this story is very touching and really brings emotional depth to the time travel plot as well as being very heartwarming in its own right. Definitely recommended for VN enjoyers.
ABSOLUTELY RECCOMEND. IM ACTUALLY SOBBING CECILIA MY BABYYYY
编剧,看完你给铯月写的结局后,我必须发自肺腑地跟你说:谢谢你让我吃到糖味的史,甜到让我心情好的跟时间之神的玩笑来的一样快!
破關後決定修改成好評 對結局挺滿意的,立繪和漫畫插圖都很不錯,音樂也很優秀(除了其中一首曲子太像圖書館的閉館音樂XD很出戲啊) 可惜的地方是結局總覺得少了一個,結合整體的遊玩體驗之後比起文字冒險我更傾向認為這是一款推理遊戲。 缺點也是有的就是遊戲性太低,錯過了很多可以放入分支的機會,反倒是序章出現許多純粹搏君一笑的選項,而且關卡設計很類似寫考卷,我想玩過的人應該就會懂我的意思,因此喜歡文字冒險的玩家可能不會喜歡本作。 文本過於刻意,有兩種層面的含意。首先是過度模仿日文句型,明明可以單純表達的內容刻意模仿日文翻譯過來的語氣。第二種是台詞太多破壞氣氛,刻意將故事主角描寫得沒什麼智慧都要靠其他人補充解釋,破壞了懸疑的氣氛。 錯字讓人出戲,首先是梳妝台的梳被寫成疏,然後撥個電話一般是寫成播打的播吧,綜合的綜變成簡體字等等。 故事裡的科幻設定對我來說也過於艱澀,很多不太能理解的地方但是也不影響遊玩體驗啦,推薦給喜歡懸疑題材和情節反轉的讀者。
It's a good read once you can put the absurdity of the game's mechanics of time travel aside and roll with it. One thing to note is that you have to reach multiple bad endings first before you can proceed. This is not immediately clear - you need to start up a new game when the cover image changes, which will partially restart the story from other characters' perspectives (adding new black cars to the train, which is plot relevant to the true ending). The best true ending (ending 0) also can only be accessed by loading up a save with the final choices after you have seen the first 2 endings, both of which have plot relevant information on how the characters can reach the true ending. This is also not immediately clear. Overall an enjoyable read.
A good short visual novel in every aspect, i recommend it. It can be done in 5 hours if you cut short or 10 hours if you take your time to read everything and try to theorize some stuff about the story of the game .
7/10 还行
