Land Run 24

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 playable browser game titled “Turbo Sprint,” a dark neon arcade endless racer viewed from a third-person, slightly elevated chase camera behind a small toy-like race car. Use a Three.js-style 3D scene with a deep navy background and fog, soft shadows, cool cyan rim lighting, and warm directional light. The player vehicle is a compact colorful racer centered near the bottom of the view, driving forward automatically on a straight three-lane road. Build the road from repeating narrow road tiles stretching into the distance; the road should visibly converge toward the horizon, with blue/cyan edge light strips and dark side barriers/runoff. Keep the camera behind and above the car, looking forward down the road, and subtly follow the car’s horizontal movement.

The core mechanic is lane dodging and boosting. There are exactly three lanes at horizontal positions approximately -0.92, 0, and 0.92. The car always moves forward automatically, while the player shifts one lane left or right at a time, clamped to the outer lanes. Smoothly damp the car toward the selected lane and slightly tilt it while changing lanes. Spawn traffic cones ahead in waves: each wave places at least one cone in a randomly selected lane and sometimes a second cone in another lane, with wave spacing gradually shortening as distance increases. Cones travel toward the player as the road scrolls. If a cone comes within roughly 0.52 world units longitudinally and 0.42 laterally of the car, immediately end the run as a crash/wipeout.

Also spawn glowing gold boost pickups/pads in random lanes ahead of the car. Represent each as a rotating gold/orange emissive ring with a bright cylindrical center hovering just above the road. When the car passes over one, remove it, add 25 score, play a short digital boost sound if available, and activate a boost for about 1.1 seconds. The boost multiplies forward travel by 1.7, increases score gain during the active period, and visibly/through the HUD increases the displayed speed. The player can also activate boost directly with the BOOST button or Space key; it should refresh the boost timer and add 25 score. Normal speed starts at 10, slowly accelerates over time up to 19, and the displayed speed is the internal speed multiplied by 12, with the boost multiplier applied while active. Distance increases by actual forward travel and score increases continuously from travel, with boosted travel worth more.

Controls: keyboard A/D or Left/Right arrows change lanes; Space activates boost. Include large touch-friendly bottom controls: a dark translucent left arrow button, right arrow button, and a wider gold BOOST button. Buttons should respond to pointer/touch input and prevent accidental scrolling. The player starts centered in the middle lane.

HUD and screen layout: overlay a fixed interface over the 3D canvas. At the top left, show a translucent navy rounded panel with cyan border reading “TURBO SPRINT” and the subtitle “lane rush // original arcade racer.” At the top right, show a matching stats panel with three columns labeled DISTANCE, SCORE, and SPEED. Initially show 0m, 0, and 0. During play update distance as an integer with an “m” suffix, score as an integer, and speed as an integer followed by “km/h.” At the beginning, show a centered translucent rounded announcement panel around the upper-middle area with the large title “TURBO SPRINT,” the message “Thread the traffic, hit the gold boosts, and survive as the road accelerates.” and a cyan START RACE button. Hide this panel after starting. At bottom right show the instruction text “A / D or ← / → to change lanes” and “Space to boost” (hide this hint on narrow mobile screens).

On collision, stop gameplay and show the centered panel again with title “WIPEOUT,” text in the form “You covered [distance]m and scored [score]. Tap below to run it back.” and change the button label to “RESTART.” Clicking/tapping it resets distance, score, speed, boost timer, lane, player position, obstacles, and pickups, then resumes play. Enter should also start/restart when not playing. Do not add lives, weapons, opponents, branching roads, laps, or extra game modes. The visual style should remain minimal, polished, and futuristic: near-black/navy UI, thin cyan borders, pale cyan text, white headings, cyan start button, gold boost button/pickups, and a clean toy-car/low-poly 3D aesthetic.
