PERSONAL NARRATIVE ADVENTURE PSYCHOLOGICAL THRILLER PC

I KNOW WHAT
YOU'VE DONE

PERSONAL GAME CONCEPT

GAME & LEVEL DESIGNER

EVERY LOOP HIDES A LIE.

Trapped in a deadly time loop, a man must uncover the truth behind a mysterious conspiracy before his past catches up with him. Explore, investigate, and manipulate conversations to piece together a story where every detail matters — and every death brings you closer to the truth.

CONCEPT &
DESIGN PILLARS

I designed I KNOW WHAT YOU’VE DONE, a narrative-driven psychological thriller built around a deadly time loop, where exploration, dialogue and player knowledge shape the investigation.

My work covers the game’s narrative structure, level design, interactive dialogue systems and gameplay mechanics. The main challenge was to create a coherent experience where each loop reveals new information, encourages experimentation and allows players to approach familiar situations with a different understanding.

TIME LOOP DESIGN

Designed a repeating narrative structure where player knowledge persists across loops. Each iteration introduces new opportunities to investigate, anticipate events and alter the course of familiar situations.

INTERACTIVE NARRATIVE

Structured branching conversations, character relationships and information reveals. Dialogue choices allow players to uncover contradictions, confront characters and progressively reconstruct the events behind the mystery.

LEVEL & EVENT DESIGN

Designed interconnected narrative locations and scripted events, from the opening hall to the car journey and gas station. Player movement, character encounters and event timing support exploration and dramatic tension.

INVESTIGATION & INTERACTION

Developed investigation mechanics built around environmental exploration and a smartphone interface featuring messages, contacts, photographs and contextual interactions. Information becomes a tool for unlocking new dialogue possibilities.

PERSUASION
& PLAYER AGENCY

Designed the FOCUS System, a persuasion mechanic that transforms information and character understanding into interactive dialogue challenges. Players must identify opportunities to influence conversations and uncover hidden truths.

SELECTED CHAPTERS

THE SAME PLACES. DIFFERENT TRUTHS.

In I KNOW WHAT YOU’VE DONE, familiar locations become the foundation of a constantly evolving investigation. As players uncover new information, revisit conversations and anticipate scripted events, each environment reveals new possibilities.

The challenge is not simply to explore these spaces, but to understand how knowledge can transform the way players interact with them.

THE HALL

THE BEGINNING OF EVERY LOOP

The starting point of the time loop and the player’s first opportunity to investigate.

This seemingly ordinary location introduces exploration, environmental interactions and the consequences of waiting or taking action. Remaining in the hall can lead to a deadly encounter, establishing that the world continues to evolve even when the player does nothing.

THE CAR

CONVERSATIONS UNDER PRESSURE

A confined narrative space where character relationships, hidden motives and dialogue choices take center stage.

As the car follows its route, conversations and events unfold within a controlled timeline. Players must observe, question and use knowledge acquired in previous loops to uncover contradictions and access new information.

THE GAS STATION

THE INEVITABLE CONFRONTATION

A pivotal location where the investigation collides with a deadly threat.

The arrival of a mysterious biker transforms the scene into a race against time. By revisiting the events leading to this encounter, players can progressively understand the danger and search for ways to influence its outcome.

GAMEPLAY FEATURES

Explore, investigate and manipulate conversations in a psychological thriller where knowledge is your greatest weapon. Every discovery opens new possibilities, allowing players to challenge the course of events and uncover the secrets behind a deadly night.

TIME LOOP

Relive the same sequence of events while retaining the knowledge acquired in previous loops. Anticipate character actions, uncover hidden connections and discover new opportunities through different choices and interactions. Use what you’ve learned to influence conversations, alter the course of events and progressively challenge an apparently inevitable outcome. Each new loop brings you closer to understanding the truth and finding a way to break the cycle.

SMARTPHONE INVESTIGATION

Use an interactive smartphone to access messages, contacts, photographs and other clues throughout your investigation. Examine conversations, uncover hidden details and piece together information gathered across multiple time loops. Connect seemingly unrelated discoveries, confront characters with what you’ve learned and unlock new dialogue options and narrative possibilities. Each piece of evidence can change your understanding of the story and bring you closer to uncovering the truth.

BRANCHING DIALOGUES

Navigate conversations shaped by player choices, previously discovered information and knowledge acquired across multiple time loops. Question characters, challenge their statements and expose contradictions to gradually uncover their secrets and motivations. Adapt your responses to the situation, use collected evidence to unlock new dialogue options and influence how others react to you. Each conversation can reveal unexpected clues, open alternative narrative paths and reshape your understanding of the story.

FOCUS SYSTEM

Spend Focus to analyze a character’s emotional state and understand what they truly feel beneath their words. Identify whether they are lying, nervous, guilty or honest by observing subtle reactions and behavioral cues. Use these insights alongside knowledge acquired during previous time loops to choose the most appropriate dialogue approach. Reading people comes at a cost, forcing you to carefully manage your limited Focus and decide when uncovering someone’s true feelings is worth the investment.

ENVIRONMENTAL INVESTIGATION

Explore detailed environments, interact with meaningful objects and uncover clues hidden within seemingly ordinary spaces. Inspect your surroundings, examine suspicious items and discover information that may initially appear insignificant. Use knowledge acquired during previous time loops to recognize new connections, unlock additional interactions and reveal secrets that were previously overlooked. As your understanding of the story evolves, familiar locations take on new meaning, turning environmental exploration into an essential part of your investigation.

GPS ROUTE ALTERATION

Although players never take the wheel, they can influence the journey by changing the destination through the car’s GPS. Different routes lead to new locations, encounters and narrative events, offering alternative ways to gather information and progress through the investigation.
