Press release:
SÃO PAULO, Brazil, 17 September 2026 | Publisher Critical Leap and indie developer Mother Gaia Studio are excited to announce that their critically acclaimed time-loop murder mystery, The Posthumous Investigation, is out today on Nintendo Switch and Android! Step into the role of a private investigator faced with an unusual case. It’s up to you to solve the mystery before the clock resets.

Your Client Is…The Victim
Play as an investigator hired by a rather unusual client: an influential entrepreneur who’s already dead. The task? You have a single day to solve the mystery of his murder. The story unfolds in a noir version of 1937 Rio de Janeiro, where each suspect has their own routine, secrets, and motives. Players observe these characters, question their actions, and use each loop to learn more about the case. 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 dirty alleys and postcard-perfect scenery, searching for notes, documents, or anything that serves as a clue. 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 before making your final accusation.

A Hand-Drawn Noir World
Your investigation sends you through a hand-drawn 1937 Rio de Janeiro that drips with style, sarcasm, and atmosphere. In this reimagining of the work of Brazilian author Machado de Assis, there is no single correct answer for this world-weary detective. Every accusation has its logic, and the truth is yours to define.

Out Now on Nintendo Switch and Mobile Devices
The Posthumous Investigation is available today on Nintendo Switch and Android devices. Mother Gaia is thrilled to bring the game to more audiences, introducing new players to this homage to Brazilian storytelling. According to Bruno Toledo, Game Director of Mother Gaia:

Bringing The Posthumous Investigation to other platforms is something we have dreamed about as a team for a long time. We’re so happy that more people can now enter this world inspired by Machado de Assis. We hope the game can be part of the little moments in their day and make the investigation feel even closer.

Gameplay Features

Master the Time Loop: You only have one day to solve the crime, but unlimited attempts to try new approaches and test different theories.

Question Everyone: Fourteen characters with distinct routines, stories, and motivations can be observed and interrogated to uncover who truly wanted the client dead.

The Thinking Board: Track the progression of the case by checking your board.

Interrogation & Dialogue: As you move through the time loops, unlock new paths, confront characters, and find the cracks in their alibis.
