About Lucifer Within Us

✦ AI summary

Solve intricate murder mysteries by investigating suspects, analyzing contradictions in their testimonies, and deducing who's possessed by digital daemons in this pure deduction game with no randomization or story tricks. Every case demands genuine detective work where you gather evidence, question witnesses, and determine the truth yourself before deciding who to exorcise in a dystopian city governed by enforced purity.

Everyone is a suspect. Unmask their lies. Choose one to purge.

Lucifer Within Us asks you to solve player-directed, story rich mysteries with your wits, making observations and deductions in a world of daemonic possession and invasive soul-scanning technology.

From the creator of The Shrouded Isle.

Investigate timelines.

Question your suspects. Watch their movements and testimonies closely, as the reconstruction may be based on lies. Use contradictions and clues to form your own hypothesis. Who is lying and why? Who is possessed? You must decide what is the truth for yourself, based on the evidence presented.

Real mystery-solving.

No hidden plot twists, no QTEs, no random puzzles or mini-games, just you and the information. In all 3 cases, don’t just act like a detective -- BE a detective. Finding the murderer will require true understanding of the case, not just following the story.

Banish daemonic A.I.

Enter the minds of citizens to gain insight into what they don’t want you to know. Dig through their subconscious and accuse the guilty in order to cast out their daemons, for the good of the Inquisition. Any damage done to a citizen’s psyche as a result of quarantine, exorcism, or rehabilitation is a consequence of their own immorality.

Expose the False Utopia.

Through centuries of indoctrination, humanity is taught to think pure thoughts and speak true words, untainted by falsehoods and delusions. Yet beneath this facade of purity, you find dark desires stir deep within people’s hearts, yearning for release.

As a digital exorcist working for the Church of Ain Soph’s Inquisition, it is your duty to find sinners and ensure continued harmony. Digital daemons corrupt the network cause human hosts to act on secret desires and sins, even unto murder. Discover the One Truth to determine which citizens are infected and exorcise the possessed.

Built on the rubble of the Old World, the last human city has become a utopia of progress, digitization, and art. The Church guides citizens towards advancement and Truth with the aid of a digital consciousness network.

Use all of the tools at your disposal to find the truth, wherever it may hide… and beware the lies you tell yourself.

Unsatisfying, short, and left me wanting more

Not very long, but a good roster of well-crafted mysteries. The timeline system is very unique, and I appreciate that there are multiple ways to reach the right answer.

A very short game, would recommend buying on sale. Otherwise it has interesting mechanics, a unique art style and some interesting workbuilding/writing. Would recommend.

This is a fun, though *very short* game. A mix of far-future technology, faith, and mystery, which definitely whetted my appetite for more. . . but the game consists of being walked through the starter case, and two more cases, and then *it's done*. Definitely catch this marked down on Steam sale; the art is delightful, and I enjoyed the world-building and voice acting. But so, so short. :P

I personally really enjoyed my time with this game. I had a very good time with the deduction sections of the game, and I could overlook most of the rough edges that made themselves known in gameplay (audio issues, primarily). I thought that the story and general aesthetic was fascinating, but it wraps itself up very quickly. I'm sure there was some sort of rushed deadline, unfortunately. That being said, I can't say I would recommend the game at full price, and I really don't often think that. But for the runtime being so short, $20 is a hard pill to swallow. I was gifted this game while it was only $3, and while it was a very fun gameplay loop, it's abrupt end left it on a sour not. I really do like this game, don't get me wrong, but I would've been extremely disappointed to have paid for it at full price for what I got.

It just goes on and on and on. There's no straightforward way to get to the bottom of these little detective moments, and the pacing is just so... so.. slow.
