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 Jul 30 → 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
Murder on the Marine Express is a kinetic novel (linear, no choices) and the first installment of The Mysteries of Ranko Togawa series.
The St. Joachim Academy for elite girls booked the maiden voyage of the new Marine Express submarine train, which runs along the ocean floor from California all the way to the Japanese coast. The journey seems like the perfect opportunity to enjoy the beautiful underwater scenery, learn about marine biology and, ultimately, relax from regular school life. However, the idyllic travel turns into a nightmare when one of the teachers is found dead in his room. Who could have killed the most popular and beloved professor in the academy?
Ranko Togawa, accompanied by her friend Astrid, takes it upon herself to investigate the events and clear the name of the main suspect. Of course, it won't be that simple. As the number of victims grows, the possibility of facing a serial killer becomes more real and panic slowly sets in. Ranko will have to make the most of the time left to find out the truth and prevent the mysterious murderer from killing again, although not all the answers will be to her liking.
Learn the secrets hidden in the Marine Express and discover the culprit in this story of tragedy, surprises and lots of humor!

Reviews
A solid visual novel carried by a memorable cast, with a simple but appealing, unique art style. It handled some complicated themes in a very serious but also easy to digest manner, which made me feel good at the conclusion. Ranko and Astrid are lovely characters and i'm very much looking forward to their next adventures.
雰囲気が良い感じの短編ミステリ、大体一時間程度でクリアできるビジュアルノベル 話としてはそれほど複雑ではなく、トリックなどもない、どちらかと言えばキャラ重視 相棒枠のアストリッドが良い味を出している、個人的に好きなのが不憫枠なブラウン先生 ワンコインでちょっとミステリを楽しみたい気分なときにおすすめ
