Press release:
SÃO PAULO, Brazil, 31 March 2026 | Mother Gaia Studio is pleased to announce that their time-loop murder mystery, The Posthumous Investigation, is out now on Steam! Stroll through this 1930s thriller to find out who has a motive, and who’s just wasting your time.
The Client Is The Victim
Play as a private investigator who’s been hired by a rather unusual client: an influential entrepreneur who’s already dead. The task? You only have a single day to solve the mystery of his murder. Adventure through a hand-drawn, noir-drenched 1937 Rio de Janeiro and learn about the lives of a cast of unique characters. Question their actions, challenge their motives, and manipulate their routines to uncover as much information as you can. When the day resets, take your knowledge with you through the time loop to stay one step ahead of the killer. In The Posthumous Investigation, death is the client, and time is your only weapon.
Gather The Evidence
Venture through back alleys, explore abandoned lighthouses, and browse through books to gather clues in this 2D side-scroller. Once you’ve unearthed all the evidence, it’s up to you to piece it together and reconstruct the timeline; only then will you be able to properly accuse the culprit. Use the knowledge you gain from your different time loops to unlock new paths, confront characters, and break open their alibis. Utilize your “Thinking Board” to keep everything you’ve learned organized, and once you’re ready, confront the killer!
A Living Literary World
The Posthumous Investigation is a satirical, witty, and dark adaptation of Brazilian literature by the legendary author Machado de Assis. Featuring characters from classic novels like “The Posthumous Memoirs” and “Dom Casmurro”, it pays tribute to fantastic works of fiction while maintaining the wit, style, and sarcasm of the original author.
Gameplay Features
Master the Time Loop: You have 24 hours to solve the crime, but infinite chances. If you make the wrong choices, restart your day and try again.
Question Everyone: Explore the secrets, stories, and motives of 14 characters to see who truly wants your client dead.
The Thinking Board: Use your physical evidence board to manually connect clues and reconstruct the timeline.
Interrogation & Dialogue: As you move through the time loops, unlock new paths, confront characters, and find the cracks in their alibis.
Hand-Drawn Noir-Drenched World: Enjoy a stylized, hand-drawn art style that captures the aesthetic of 1930s Brazil.
