The animal masks do more than hide twelve faces. They make it easier to forget there are twelve ordinary people underneath them. Mouse, Ox, Tiger, Bunny, Dragon, Snake, Horse, Sheep, Monkey, Rooster, Dog, and Pig quickly become identities in their own right, and The Zodiac Trial exploits that distance constantly. Someone I trusted as an ally in one route could become terrifying under a different set of circumstances, which made every label feel less like a personality type and more like a role waiting to crack.
Mouse is the only one I control directly. She is a law student kidnapped alongside eleven other people, fitted with a metal collar, assigned her zodiac alias, and forced into the Zodiac Race by a masked figure calling himself the Jade Emperor. The captives move tokens around a physical game board while following rules designed to turn cooperation into something increasingly difficult to maintain. Surviving requires understanding the game, but understanding the people playing it matters more.
That is where the enormous branching structure earns its size. There are thirteen major scenarios rather than one central story with slightly different casualties. A route can become a murder investigation, a struggle over alliances, a political fight for control, or something much more openly violent depending on decisions made earlier. I stopped assuming I understood any character after seeing how differently the same person behaved when the circumstances around them changed.
Horse demonstrates that especially well. His size and physical strength make him easy to read as dangerous before he says much at all, but strength does not automatically determine what kind of person he becomes in a given route. Ox presents the opposite problem. He is composed enough that his reasoning can feel reassuring until I start wondering how much of the room he has already calculated. Snake is difficult to read for entirely different reasons, while Rooster’s more foolish behavior can make him easy to dismiss at exactly the wrong time.
The clever part is that these are not twelve fixed archetypes being dropped into interchangeable stories. Each route places pressure on different weaknesses. Someone generous under one arrangement can become selfish when the rules reward selfishness. A character who seems suspicious elsewhere can become the person Mouse most needs to trust. The game kept making me revise judgments I had already decided were settled.
Its fifty-plus endings amplify that uncertainty. Most major routes have several outcomes, with Death Cards tracking the many ways Mouse and the others can fail to escape. Some endings arrive brutally quickly, while others require a sequence of decisions that only becomes understandable after seeing more of the game. Completion is a serious commitment, especially because The Zodiac Trial does not provide the kind of built-in flowchart that would make jumping between branches painless.
That absence becomes noticeable once information starts carrying between playthroughs. Certain routes assume I remember details uncovered somewhere else, and eventually the mystery starts rewarding knowledge rather than simply choices. I liked having to remember what I had learned because it made repetition feel purposeful, but navigating back toward a specific branch can be cumbersome when I know exactly which section I need and still have to work through earlier decisions again.
The puzzles are lighter than the death-game premise initially made me expect. There are riddles, investigations, deductions, and situations where Mouse has to identify inconsistencies, but this is primarily a text-heavy visual novel rather than an adventure game built around mechanical puzzle solving. Wrong answers do not always mean immediate death either. Other characters can intervene, argue, or redirect the situation, keeping the focus on how the group reacts rather than turning every question into a pass-or-fail test.
Monkey’s hypnotherapy adds one of the stranger layers to that structure. The sessions let Mouse mentally work through variations of the Trial, giving the game’s alternate possibilities a place inside the story rather than leaving them as completely disconnected save files. I liked that approach because thirteen wildly different scenarios could otherwise have felt like the game simply resetting reality whenever convenient.
The larger mystery gradually gives those variations a common purpose. The Jade Emperor did not choose twelve random people, and Mouse’s legal background becomes increasingly important as connections between the jurors begin surfacing. I was much more interested in discovering why this particular group had been assembled than in trying to guess the mastermind immediately. The strongest revelations come from realizing that relationships I had treated as isolated were part of something shared long before anyone put on an animal mask.
Visually, the production is modest. Character portraits and limited locations carry a story that can run for more than thirty hours if I chase its major branches, so repetition is unavoidable. The character designs compensate by making each zodiac identity instantly recognizable, and the writing does enough with changing alliances that familiar rooms rarely feel attached to the same situation twice.
The Ren’Py presentation stays functional rather than flashy, which puts almost everything on the script. That works because dialogue is where The Zodiac Trial is strongest. People bargain, accuse, manipulate, panic, cooperate, and occasionally make choices that only become understandable after another route reveals what they were hiding.
What kept me replaying was not the promise of filling every Death Card slot. It was the uncomfortable realization that one route could make me feel certain I understood someone, only for the next to dismantle that certainty completely. The masks hide faces, but the branching structure hides something more useful: the circumstances required to reveal who each person might become.
Verdict
The Zodiac Trial earns its huge branching structure by making trust unstable from one scenario to the next. Thirteen major routes and more than fifty endings reveal genuinely different sides of the same twelve captives, although navigating them without a built-in flowchart can become cumbersome. Its presentation is simple, but the shifting alliances give this death-game mystery its real bite.
