Harbor Run

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.

Recreate “Harbor Run” as a small, original low-poly 3D city/waterfront sandbox viewed from a behind-the-player third-person camera. The scene should use a bright pale blue sky with matching distance fog, soft late-afternoon lighting, shadows, and simple stylized geometry. Build a broad dark asphalt north–south main road (about 18 units wide) with pale sidewalks on both sides, a wider east–west crossroad, and small yellow dashed lane markings. Place a blue waterfront area on the east/southeast side of the district, with simple block-shaped buildings lining both sides of the road in muted blue-gray, brown, and gray colors. Add several tall stylized palm trees around the streets and waterfront. Keep the environment sparse and toy-like rather than realistic; buildings are plain rectangular masses and the ground beyond the roads is green-gray.

The player is one blocky human character, initially positioned on the road near the camera, rendered with a low-poly/voxel-like Kenney character style: tan/orange torso and arms, a dark bluish blocky hair/head shape, and green trousers. The character casts a soft dark circular shadow. Support walking and running movement in the third-person controller: WASD or arrow keys move, Shift makes the character sprint, and Space jumps. The camera follows from behind at a moderate distance and looks toward the character’s movement direction; it should smoothly track the player and show the road extending into the waterfront district. On touch devices, provide a large translucent circular virtual joystick at lower left and a separate translucent circular action control at lower right, matching the mobile screenshot style.

Include one orange/red low-poly sports sedan parked close to the player at the start, initially around the right/front side of the character. The car should have a visible sporty body, dark windows, wheels, and cast a shadow. When the player is within roughly 5.5 world units of the car, pressing E—or using a visible mobile button—enters it: hide the character, switch the vehicle button text to “EXIT CAR,” and change the status mode from “ON FOOT” to “DRIVING.” While driving, use WASD or arrow keys: up/W accelerates forward, down/S reverses, and left/right steer; make the car smoothly accelerate toward a moderate speed, turn according to steering, and move across the road. Keep the player’s position synced to the car while inside. Press E or the vehicle button again to exit, show the character, place them just beside the car, and restore “ON FOOT.” Only show the vehicle button when near the car on foot or while driving.

Create a fixed translucent dark HUD over the game. At upper left show a rounded dark panel with the yellow, letter-spaced title “HARBOR RUN,” then the text “A small original city sandbox” and the controls “WASD / arrows move · Shift sprint · Space jump” and “E enters the sports car.” At upper right show a compact rounded status panel with “ON FOOT” or “DRIVING” and a coordinate readout such as “0.0, 18.0.” At the bottom center show a dark rounded hint bar reading “Explore the waterfront district.” Use responsive spacing so the HUD remains readable on narrow mobile screens. There is no combat, inventory, score, health, missions, or win condition; the purpose is simply to freely explore the waterfront district on foot or by sports car.”,
