About
The First Light Novel-style Immersive Detective Game!

A mysterious girl suddenly visited your detective agency, offering to be your "unpaid assistant"!
And the sheriff's arrival brought a bizarre case.
A resident was found dead in his room, the doors and windows sealed shut.
The entire apartment, punctuated by a series of interlocking testimonies, has become a locked room, impenetrable to outsiders.
In this double-locked room, why did the deceased commit suicide? And was it truly suicide?
If it was murder, who is the murderer hiding among the neighbors?
An approachable merchant, a carefree unemployed, a naive actress, a intelligent salaryman. Who is lying?
Also, who is this girl, whose origins she can't even explain by herself?
The answers to these questions are up to you to uncover.

(The murder is among them. Perhaps?)
Say goodbye to rummaging through boxes! Experience a pure battle of wits!
"How Many Secrets Under Ceiling" is a deduction game that revolutionizes traditional mystery-solving by eliminating the need for physical evidence. Solving complex cases solely through logical reasoning within the text, exploiting contradictions and loopholes in conversation, and scrutinizing details and questions in narrative. This scenario is written by a new writer with Gentosha Mystery Fiction Award, based on The Walker on the Ceiling by Edogawa Ranpo.
Unmask lies, reveal truths, and become the sole master of this linguistic labyrinth!
In the game, you don't need to play the role of anyone else; simply be your authentic self.
You'll make choices based on your own logic, preferences, and even your personal values, solving puzzle after puzzle, navigating danger after danger, and having your every thought validated.
The Honkaku Mystery is written in the style of a light novel, making you always smile!
The lively dialogue and banter save you from all the unhappiness!

Reviews
质量出乎意料的高,尽管整个游戏很多地方都很简陋,但推理部分做的真心不错(比我前两天打的魔裁强多了),[spoiler] 叙诡还蛮有意思的 [/spoiler],作为十块钱的价位的甜品作可以说是很优秀了,看评价这么少打个好评支持一下,希望能有更多推理游戏爱好者发现这款有趣的作品吧
文本质量算是很不错的,推理要素也有,但是UI奇差无比玩得郁闷,除了各种神秘位置的返回键以外,经常读着读着就不让看证据线索不让存档,关键是你问问题的时候搞这种,那我搜到的证据有啥用啊。。。
4个多小时打完了,看着空荡荡的评论区有点惋惜。我其实挺希望本作能火的,也算是开了个推理游戏新赛道吧:没有美术怎么办?主要角色们画个头像就好,再加上本身有原作,改编成“轻小说式”游戏后剧情也很扎实。不过现阶段中文还存在部分文案错误,后续也推荐加个已读快进的功能,自动存档可以设置一下,毕竟部分剧情里玩家不能存档,触发BE不能SKIP挺难受。搜查到的线索基本没融入玩法中,不过让玩家专心看故事也挺好。 一杯奶茶钱,快下单吧,买到就是赚到。
好棒的游戏!推荐! 真相有想到,但是诡计重点那里真的有被骗到,回去又看了好几遍前面的内容哈哈 就是有的时候不能点存档那些按钮不太方便,然后右上角的返回键不太明显,所以第一次点开调查的时候找了半天怎么关闭... 不过美术确实简单但是我觉得恰到好处了,有特色 应该会去看看原著,对后记提到的原著内容还挺感兴趣的
意外的在摩点筹到了有趣的游戏! 丸子居然在名单的最后一行,害我仔细看完了整个列表// 话说小女孩有点太过优秀了叭~ 看游戏名大概就能猜到是哪个案子,但是一定不要先入为主啊,因为有着完全不同的故事和内核。 内容大概就是聊天,梳理各种关系网以及进行一次侦探大冒险,最后揭开真相。 果然还是被骗了,这种东西目前一次也没有成功看出来过,每次回顾都会懊恼怎么没有仔细思考线索,可惜还是每次都会错过。
蛮有意思的推理游戏。各方面都挺简陋的:比如打了BE读档回来没有跳过按钮,还有证据列表经常不能打开和当前对话对照之类的,但是不妨碍游玩。我个人很喜欢这个小圆脑袋,可惜游戏内除了过场的CG其他地方没怎么用,要是对话里的头像也是就好了。
The english version of this game is very sadly not ready for prime time. I can’t recommend it in its current state :(.
简洁明了的示意图耶,UI确实有点不明显,希望有快进功能!
可以当作是看一个难度不高的推理小故事 [spoiler] 后面的叙诡挺有意思的 [/spoiler]但是游戏里不让快进文本特别难受 还有ui太烂了
通关了!玩到一半的时候意识到了是哪部作品的改编,从侦探的视角出发体验一次这个案件还蛮有意思的,尤其是作者团队把每个角色写得都很立体,有日式纸片人的萌点又完全不会觉得对话尴尬,旁边的吐槽也看得我很乐在其中~不得不夸的一点是写日常对话的节奏感很舒适,即使是在推理游戏里也和这些角色聊得很开心!甚至写得比很多主打日常戏份但是写得又臭又长的旮旯给木和文字游戏好多了……如果之后出非推理向的文字游戏我想也会很不错的! 画风我也完全能接受,很可爱的小朋友萌萌涂鸦,给小女孩送上一句蒸蚌!以及好想看看侦探的小人偶和房子是什么样的,在流程里萌了我六七次啊! ——天花板下的第五个秘密
