Open Road

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 endless driving game titled “Open Road.” Use a third-person chase camera behind and slightly above a sports sedan, looking forward down a long straight three-lane highway. The player car sits near the bottom center of the view, with steering visually banking the car slightly. The camera should smoothly follow the car’s horizontal movement while continuing to look toward the road ahead.

Scene and visual style: use a simple clean low-detail 3D presentation. The background is a pale sky-blue color with matching distance fog, and broad flat green grass extends on both sides of the road. Build the highway as a dark charcoal asphalt strip about 12 units wide, with pale solid edge lines and a yellow dashed center line. The road should visually continue toward the horizon, with perspective making the lane markings progressively smaller. Place occasional simple pine trees well off the roadside on alternating sides; trees and road scenery should move toward the camera as the car drives to create the endless-road illusion. Use soft directional sunlight, ambient/hemisphere lighting, shadows on cars and scenery, and subtle atmospheric fog.

Gameplay: this is an endless drive where the objective is to survive and accumulate distance. Start the player at the center lane with a base speed of 20, allow speed to range from 9 to 34, and increase the displayed distance continuously by the current speed. Spawn several AI traffic cars ahead in the three lanes. Traffic cars move toward the player relative to the road motion; when one passes behind the camera, recycle it far ahead at a random lane and distance. Recycle roadside trees in the same way. The player can move laterally across the roadway but is clamped within the road area, roughly from x=-4.1 to x=4.1. Collision with a traffic car occurs when horizontal separation is less than about 1.35 and forward/depth separation is less than about 2.5; on collision immediately end the run.

Controls: keyboard A or Left Arrow steers left, D or Right Arrow steers right, W or Up Arrow accelerates, and S or Down Arrow brakes/decelerates. Also provide large touch/pointer buttons along the bottom: left arrow, “BRAKE,” “GO,” and right arrow. These buttons should hold their associated controls while pressed and be usable on mobile. Steering should smoothly damp toward the input, move the car laterally, and slightly roll it; speed changes should be smooth and clamped.

HUD: overlay the game with no pointer interaction except the controls and game-over dialog. At the top left show a dark translucent rounded panel reading “OPEN ROAD” in bold uppercase and “ENDLESS DRIVE” beneath it. At the top right show a matching panel labeled “DISTANCE” with the current whole-meter value followed by “m.” Near the lower middle above the controls show the hint “A / D or ◀ ▶ to steer · W / S to change speed.” Use white text, blue-gray secondary text, translucent navy panels, rounded corners, and subtle shadows. At the bottom center place four rounded dark buttons in a row: left arrow, BRAKE, GO, right arrow.

When a collision happens, stop all gameplay motion and show a centered translucent dark overlay/card with the large word “CRASHED,” the message “You drove [distance] m on the open road,” and a “RESTART” button. Restart resets distance to zero, speed to 20, player position to the center, traffic/scenery positions, and hides the overlay. Keep the overall composition and feel minimal, bright, and arcade-like, matching a clear road stretching over green countryside rather than adding extra powerups, enemies, tracks, weapons, lives, or menus.
