Detective Conan 3D Case Files

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a browser-based 3D third-person detective exploration game titled “Detective Conan: 3D Case Files,” with the case header “CASE 001 · The Missing Ledger.” Use a dark, stylized low-poly nighttime city block inspired by Beika: a deep navy background and fog, a four-way paved intersection with pale yellow lane markings, light gray sidewalks, several simple colorful block buildings, and sparse geometric street trees. Include a small agency building at the far side of the block with a sign band and dark entrance, plus nearby shop and office facades. Use soft shadows, cool blue ambient/rim lighting, and warm directional sunlight/highlight for a cinematic case-file look.

The player is a suited detective character shown in third-person, initially positioned on the street near the intersection. Provide WASD movement, Shift sprint, Space jump, and mouse-look camera controls. Use a third-person follow camera at roughly six units behind the player. The player can walk around the district and approach interactable objects; show a bottom-center contextual prompt reading “Press E to interact” when close enough. Press E to interact.

Implement this exact case progression. Start with the objective “Find the witness at the Mouri Agency.” At game start, display a dialogue panel near the bottom explaining: “A delivery ledger vanished from the district. Explore the block, speak to the witness, inspect the agency, and collect the torn corner.” Place a witness character just inside the agency interior, and make the agency door enterable. When the player interacts with the agency door, move them into a modeled interior pocket/room with a floor, walls, a desk, and a wall board. Show dialogue titled “Mouri Detective Agency” with text: “The office is quiet. A witness said the missing ledger passed through this room.” Change the objective to “Inspect the ledger on the agency desk.”

Place a glowing rotating gold/orange octahedron evidence marker outside near the intersection, and place a torn ledger corner/paper on the agency desk. The evidence interaction should show “Evidence collected” and “A torn corner of a delivery ledger. The ink is still fresh.” Hide the street evidence marker when collected, increment the evidence counter, and change the objective to “Talk to the witness inside the agency.” The witness should respond with: “I saw a black sedan leave the intersection just before the lights changed.” If the witness is spoken to before the evidence is collected, direct the objective to “Collect the torn ledger corner outside.” If evidence has been collected, set the objective to “CASE COMPLETE · Compare the ledger corner with the witness statement.” Allow E near the interior exit to return the player to the street and restore the objective “Find the witness at the Mouri Agency.”

Add a black/dark sedan case car parked near the intersection. When the player approaches and presses E, enter driving mode, show a “Vehicle” dialogue saying “You are driving the case car. WASD to steer and accelerate. Press E to exit,” and switch to a vehicle-follow camera. In the car, W/S accelerate and reverse while A/D steer; constrain the car to the district bounds. Press E to exit and place the detective beside the car. The car should be a visible imported or low-poly sedan, while the player character remains visible when on foot.

Use a fixed HUD overlay with translucent dark navy panels, thin blue-gray borders, rounded corners, subtle shadow/blur, and white/cyan typography. Top-left: cyan “DETECTIVE CONAN,” a blue pill badge “3D CASE FILES,” and “District 01 · Beika-inspired block.” Top-right: “CASE 001 · The Missing Ledger” and the current objective, initially “Find the witness at the Mouri Agency.” Bottom-left: “WASD move · Shift sprint · Space jump · Mouse look · E interact / enter car · Esc pause,” followed by a gold “Evidence:” label and an evidence count displayed as “0/2” initially. Bottom-center: interaction prompt when applicable. Above it, use a wide dialogue panel for temporary case dialogue and automatically hide it after several seconds. Escape toggles pause. Maintain the subdued navy, cyan, gold-evidence visual identity and a clean atmospheric low-poly detective-game presentation.
