Velocity Circuit

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 3D arcade racing game titled “Velocity Circuit” in a dark neon night setting. Use a third-person chase camera behind and slightly above the player’s compact sports hatchback, looking down a long straight roadway; smoothly follow the car as it moves forward, with a subtle lateral camera offset and the road disappearing into blue fog. The scene should use a deep navy-black background, soft atmospheric fog, cool cyan lighting, shadows, and glossy low-poly/clean stylized city visuals.

Build a very wide straight racing road running along the z axis, approximately three lanes wide, with dark blue-gray asphalt, bright cyan glowing edge rails on both sides, a dashed white center line, and intermittent cyan glow strips near the edges. Add a white start line near the beginning. Place low blocky city buildings in dark blue, purple, and indigo on both sides, plus repeated curved double street lamps along the roadside and one highway sign. Keep the playable road bounded so the player cannot leave it.

The player drives a cyan/blue sports hatchback starting near the beginning of the road. Use a visible imported or stylized sports-car model, oriented forward down the track. Add a bright cyan underglow/boost visual that appears beneath or around the car while nitro is active. Include three rival sports cars ahead/around the player, colored hot pink/red, yellow-orange, and purple. They move forward continuously at different speeds, wrap back to the start when they pass the far end, and gently sway side to side around their lanes. Colliding with a rival should reduce the player’s current speed and subtract a small amount of score, without stopping the race.

The core goal is to complete three laps by driving forward along the road. The track is implemented as a looping long straight: when the player reaches the far end, increment the lap and reposition them near the start. End the race after lap 3 and show a centered finish overlay containing “FINISH · SCORE [score]” and a checkered-flag symbol. Start with a prominent centered countdown: show 3, 2, 1, then GO, with “GET READY” beneath it; disable driving until the countdown completes.

Driving controls: W or Up Arrow accelerates, S or Down Arrow applies reverse/braking acceleration, A or Left Arrow steers left, and D or Right Arrow steers right. Space activates nitro only while the car is moving above a low speed threshold and while boost remains. Normal speed is capped around 27 game units, nitro speed around 40; nitro rapidly accelerates the car and drains the boost meter, while not using nitro gradually refills boost. Steering should smoothly interpolate toward the held direction, move the car laterally, and clamp it within the road. Releasing acceleration should make the car decelerate. Also provide mobile touch controls: circular left and right arrow buttons at the lower corners and a pill-shaped NITRO button near the lower right; hold behavior should match the keyboard controls. Do not show touch controls on wide desktop layouts.

Scatter 20 floating cyan energy pickups down the road at alternating lane positions. Make each a glowing rotating cyan octahedron. When the player gets close, hide the pickup, add 25 boost energy up to a maximum of 100, and add 250 points. Pickups remain available when a new game/reset starts. Rival collisions reduce score by 15 but never below zero. Display speed as rounded KM/H, lap as 1/3 through 3/3, and a fixed position indicator of 1/4 in the HUD.

Use a fixed overlay HUD with a sleek glassmorphism style: at the top left, a rounded translucent dark-blue panel with cyan uppercase “VELOCITY CIRCUIT,” a large speed number followed by KM/H, and “LAP 1/3 · POS 1/4.” At the top right, another rounded translucent panel labeled NITRO with a horizontal boost bar that gradients from cyan to purple and text “WASD / ARROWS · SPACE BOOST.” At the bottom center show the hint “Drift through the neon gates. Collect cyan energy for boost.” Center countdown/finish text should be large, bold, white and cyan with strong shadow. Match the screenshot’s polished futuristic arcade presentation: near-black navy page, cyan and purple accents, rounded outlined controls, high contrast typography, and no debug UI.
