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.

Reviews
bgm虽然少,但还比较耐听,游戏画风也挺可爱的,十块钱左右的价格有十几万字的剧情,人物塑造得挺鲜活的,剧情也是层层推进,除了讲究逻辑推理的案件,里面也有不少有趣的吐槽,所以虽然几乎是纯文字游戏,也还是像轻小说一样,能吸引我玩(读)下去。 推理部分容错率还比较大,再结合存档读档大法,不怎么玩推理游戏的人也能轻松上手。总体来说还是推荐感兴趣的人试一试的。 (以下部分有剧透!) 不过关于叙事方式上的一些巧思,就见仁见智了,比如全程刻意不挑明红砂和房东是一个人这种,我个人不太喜欢,我更喜欢把推理的心力放在案件本身上。 还有小女孩的真实身份,虽然尾声里,她以穿越者的身份说的那些话也挺有意思的,但是感觉……在讲究逻辑和科学推理的探案游戏里,安排一个从未来穿越而来、引导侦探办案的助手这一点,有点出戏了。
虽然游戏价格很便宜但我不觉得游戏质量是能收费的程度,游玩过程一度让我觉得自己在玩橙光,故事本身来说一是改编,二是作者逻辑比较明显吧,叙诡是和中低水平剧本杀坐一桌的程度。再说操作过程,必须记得存档不然就要鼠标连点器重新看一遍大段冗长的对话,不如花这个时间多看两本日本推理
