April 2026
It was neat to play a detective game that was based on a book that isn’t sherlock holmes 😂 and in Brazil too! It is what it says on the tin. So if you’re already leaning towards buying it just looking at the store page, big thumbs up! Also big thumbs up because it’s from an indie studio in Brazil based on work by a Brazilian writer. I’m going to complain about a few things though: - “No hand-holding” is a lie. This could’ve been detective curse of monkey island except every time you restart your timeloop the dead guy talks you through all your evidence and explicitly tells you what to do next lol. So do the tooltips for clues you’ve collected. So do the profiles for all your suspects. Like lol, I had to stop looking at my inventory and stop talking to the dead guy entirely just to have any amount of agency. - Back half quickly turns into into a gopher simulator, where you’re running around doing the 4 steps that you need to talk to a specific character, then speeding up time to get to the specific character to show them the one clue, then starting your day over and doing it again with another clue and character. I went into the forking alley to get that forking key like 50 times. The game wayyyyyy outstays its welcome. - This isn’t a gripe with the game, more with the source content i guess: 80% of the plot development is just doxxing people’s infidelity. I don’t think that’s very interesting at all, especially not this much of it. Please limit yourself to 1-2 sordid affairs in any sequels 😭.

It's an excellent game, but could be better with some QoL improvements. Given the amount of repetition, I wish I could skip some dialogs that I had to read like 10 times

This is one of the most fun detective games I've played in years, along with Detective Grimoire and Duck Detective. I would say even better than one of these two. The noir Rio de Janeiro vibes and aesthetics, the voice acting and specially the sound design, all very polished and perfect combined with the fun mechanics and great storytelling. It's definitely a gem of a game. I may revisit the book because of It.

I loved this game: Genuinely, completely, without reservations! Brás Cubas is dead and he also hired you from beyond the grave to solve his murder, which is either the most baroque power move in the history of detective fiction (or a very on-brand final act for someone who spent his entire life refusing accountability lol). The setup is deceptively simple: one day, fourteen suspects, a time loop that resets at midnight. Every NPC has their own schedule, their own secrets, their own reasons to be somewhere they shouldn't at exactly the time you need them elsewhere. Nobody is innocent. Nobody is entirely guilty. And everyone, somehow, manages to be completely likeable despite your growing certainty that they are lying to your face. The NPC cast is the real argument for this game. These are not clue dispensers with names attached. They are people with histories, contradictions, and the kind of charisma that makes you genuinely reluctant to accuse them even when the evidence points directly at their door. The writing holds them together with a tone that is witty, sharp, and emotionally precise without ever becoming sentimental. The twists are earned. The hand-drawn art depicting 1937 Rio de Janeiro is, quite simply, beautiful. The soundtrack knows exactly when to stay out of the way. For fans of Glass Onion, Knives Out, Agatha Christie, or anything where the best part is watching a room full of fascinating people slowly run out of places to hide, the recommendation is immediate. The investigation is rigorous enough to be satisfying and accessible enough to not require a notepad. The Thinking Board handles your loops with quiet elegance. And here is the more important pitch: this is your chance. Machado de Assis is considered by many the greatest writer in Brazilian literary history, and for most of the world he remains an unread name. The Posthumous Investigation is a remarkably painless entry point into his universe, witty and sharp and deeply skeptical of everyone including the narrator. If any of that sounds familiar, it is because the game learned it directly from the source. Play it, enjoy it, and then maybe pick up Dom Casmurro. You have no more excuses.
