Inspiration

Inspired by Ace Attorney and our love for philosophy, we wanted to push the idea of justice to an absurd extreme by applying a serious courtroom system to the pettiest disputes, from stolen pens to unread messages. If law exists to resolve society’s greatest conflicts, what happens when we use it to settle the smallest ones?

What we built

We created a multiplayer courtroom game where players act as biased witnesses instead of debaters. Each player holds secret evidence and uses it strategically to influence a strict AI Judge, turning small personal conflicts into dramatic trials. The focus is not on winning through popularity, but on how evidence, timing, and narrative can shape a judge’s perception.

What we learnt

We learned how challenging it is to make an AI feel consistent and believable in a game setting, especially when players are intentionally biased and strategic. This pushed us to think more deeply about how memory, context, and evidence should be represented so that the judge feels grounded rather than random.

Challenges

Our biggest challenge was getting the judge to actually follow the judicial framework we designed. We experimented with a GraphRAG-style memory system to help the judge track evidence and claims, but found it difficult to make the reasoning behave reliably and intuitively. Making the judge feel disciplined without becoming rigid, and intelligent without becoming unpredictable, was the hardest part of the project.
