Sundown Rush

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 3D endless driving game titled “Sundown Rush.” Use a third-person chase camera positioned behind and slightly above the player car, looking down a straight three-lane highway that recedes into the distance. The scene should have a cinematic sunset appearance: a warm orange/tan sky and environment, dark brown background tones, atmospheric fog, ACES-style filmic tone mapping, a strong warm directional sun from the front-left that casts soft shadows, and subtle warm hemisphere fill lighting. Use a low-poly/stylized car-asset look with a race car for the player and varied sedan/sports and hatchback/sports cars for traffic.

Build an endlessly scrolling road. The highway is a dark charcoal asphalt strip about 11 units wide, bordered by a much wider ochre/golden shoulder or ground plane. Mark the two lane dividers with regularly spaced pale cream rectangular dashes, and place continuous pale edge lines on both road sides. Divide the road into repeated 60-unit segments and recycle segments behind the camera as they move forward, so the player appears to drive forever on a straight road. Keep the player car at the camera’s origin in the travel direction, facing toward the negative-Z distance; move the road and traffic toward the player to create the motion effect. The camera should gently follow the car’s horizontal movement and look toward the road ahead, with a slight cinematic sway/follow feel.

The player drives a race car in the center lane at the start. Allow continuous horizontal steering across the road using Left/Right arrow keys or A/D; on touch devices show two translucent circular controls at the lower-left with left and right triangle icons. Steering should be smooth rather than an instant lane snap: clamp the car’s horizontal position to approximately -4.2 through +4.2, tilt/yaw the car slightly into the steering direction, and give it a small roll. There is no braking, reversing, shooting, drifting, boost, jump, or lane-change button beyond horizontal steering.

Spawn eight traffic cars ahead in the three lanes, alternating between the two traffic body styles and tinting them in varied colors such as red, blue, gold, purple, and green. Traffic travels in the same direction but more slowly than the player, so it approaches the camera as the player’s speed increases. Randomly assign each traffic car to one of the three lanes and respawn it far ahead in a random lane after it passes behind the player, with varied slower speeds. The core goal is to dodge all traffic for as long as possible. Detect simple approximate car collisions using horizontal and longitudinal distance; if the player overlaps a traffic car, immediately stop the run and show a wreck screen.

When the game first opens, display a full-screen dark translucent overlay over the sunset scene with a centered glowing title “SUNDOWN RUSH,” the message “Dodge traffic. Speed builds forever.” followed by “◀ ▶ or A / D to steer,” and a large rounded orange gradient button labeled “DRIVE.” The overlay should have white text, a warm orange glow around the title and button, and a slightly blurred backdrop. Clicking DRIVE hides the overlay and starts the run. During play, show a minimal fixed HUD: the score as a large white number at the top-left (starting at 0), and speed in km/h at the top-right (starting at 0 km/h). Increase score continuously based on travel speed. Start the world speed at 26 units/second and automatically accelerate over time up to 70 units/second; display the converted speed as speed × 3.6 in km/h. There is no finish line or level progression.

On collision, stop movement and replace the overlay title with “WRECKED.” Show a message in the form “You crashed at [speed] km/h” and “Score: [score],” and change the button text to “DRIVE AGAIN.” Pressing it resets score and speed, returns the player to the center, redistributes traffic far ahead, and starts a fresh run. Preserve responsive full-screen rendering and adapt the camera aspect ratio on resize. The overall presentation should remain clean, minimal, warm, atmospheric, and arcade-like, matching the visible dark sunset highway and simple HUD rather than adding extra menus, weapons, powerups, curves, or gameplay systems.
