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): 0.14/day in the week to Aug 16 → 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.

It is a delightful game that almost plays like a show(with the intro and recap and such). I do hope the developers will continue expanding on the story as I would like to find out more about their backstories and these hearts. The game focuses on the death of the girl's father and who the killer is while adding some hints of darker things that went on. There are three episodes that are split into 'cases' that you can select from at the start. The music is very enjoyable and catchy and I did enjoy the humour that went along with this. The personality of the characters work very well, especially the dynamic between Lynn and Arne. It does not feel like the characters have to compromise, they are who they are. The art is visually appealing and clean and there is a lot of expression with their pixel forms too. The little extras were not expected but very much appreciated. It felt like the developers were experimenting with the limits of RPG Maker by adding all sorts of minigames to keep it entertaining and refreshing. I also appreciated that it does not matter if you make a mistake as you can still play through the story but you are rewarded if you make no mistakes with some extra goodies. In regards to an issue I had... It was the character movement being a bit slippery? Fortunately the game is not difficult and is very kind to you although, there are times you will have to be a little precise with your movements. I think it was made with the minigames in mind in terms of the movement(just a guess). It is not really a problem however you will come to notice it. I think the movement speed is great but it comes at a cost of control, just a little bit. You will know what I mean when you play it. You can live with it though! For the price of the game, I think it is certainly worth it. For some, this game may be considered short but I think the length of it is quite appropriate for it. It honestly felt like a passion project as a lot of energy and care went into making this game. I really enjoyed it and would happily buy the next case if it were to come out. (It is hinted at the end of the game.) It felt like I was watching an anime episode. Keep that energy! Please continue with this and thank you~ It was a fun experience. ^-^/) (Also Lord Arne's smooth line delivery with the cg about his heart was really cool. Not spoiling~)

이 게임을 접한지 5년이 넘은 것 같은데 이 게임 덕분에 현실 흡혈귀가 되려고 하고있습니다...
리뷰 평 보고 예상한 거보단 재밌었는데 막상 기대한 거보다는 별로였다 오글거리는 거야 쯔꾸르 게임 중에서 안 오글거리는 게임이 없으니 별 생각이 없었는데, 미니게임도 너무 난잡하고 재미가 없고, 추리 하나를 3부로 쪼개놓아서 집중이 하나도 안 되는 구성에, 3부로 나눠 놓았으니 각각의 파트에서는 진도가 너무 안 나간다. 이 동네 귀족은 권위가 편의점 사장만도 못하다. 하다못해 편의점 점주도 직원이 폐급이면 바로 잘라버릴 텐데, 이 세계 귀족네 집 고용인이란 작자들은 하나같이 일을 제대로 하는 사람도 없고, 귀족이 죽었는데 잘 죽었다고 신나하고 있으며, 마지막 엔딩 때는 "아 아가씨 망하셨구나 ㅎㅎ ㅠㅠ 어쩔수없죠 마지막으로 남은 재산은 제가 훔쳐갈게요 안녕히 계세용!!!' ㅇㅈㄹ하는 꼴을 두고 보고만 있다. 사실 귀족이라는 건 호구와 같은 말인 걸까? 어떻게 경비 못하는 경비병, 집안일 못하는 메이드, 보좌 못하는 집사, 주인이라도 요리 안 먹으면 분노하는 요리사, 주인 버리고 메이드한테 야반도주하자는 정원사가 한 집안에 공존할 수 있단 말인가? 오글거리는 건 참아도 이건 도저히 못 참겠다. 그런데 하도 기대치가 낮아서 그런지 생각보다는 재밌었던 거 같다. 이미 잔뜩 실망할 준비를 하고 들어가서인지 생각보다 캐릭터성이나 추리 파트는 나쁘지 않았던 거 같기도 하다. 3부 구성만 2부 정도로 좀 줄였으면 더 재밌었을 거 같은데 아쉬울 따름이다.
The overworld, the controls, and the mini games are very much RPG Maker. However, that does little to dampen the lovely character art and the deeply intriguing story! So much fun, I played it in one sitting! Looking forward to seeing if the anime can do it justice!
Boring
好想玩后续
神作,男女主好萌,什么时候把后面几章搬上来啊!!
Ich finde es schade das es keine Deutschen Übersetzung hat
Ive played a lot of RPG maker games and this one was def a gem, but is slightly different than other popular ones like IB or the witches house. The case book of arne is more so a visual novel with some small minigame segments so if you dislike lots of reading instead of exploring, this isnt for you. 10/10 mystery 10/10 vampire
