Turbo Loop

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-playable 3D arcade racing game titled “Turbo Loop.” Use a bright low-poly/toy-like visual style with a sky-blue background and fog, a large vivid green grass field, and a dark gray asphalt oval circuit. The track should be an elongated oval roughly 84 units wide by 56 units deep, about 12 units wide, with a white finish stripe across the track at the back, and evenly spaced short yellow center dashes around the racing line. Use a third-person chase camera behind and above the player car, smoothly following its position and looking ahead in the direction of travel. Light the scene brightly with soft shadows.

The player drives a red Kenney-style low-poly race car (or a simple red toy race car fallback) starting at the back-center of the oval, facing forward around the loop. The car has acceleration, braking/reverse, steering, friction/coasting, and speed-limited movement. Controls: W or ArrowUp accelerates; S or ArrowDown brakes and can reverse; A/ArrowLeft and D/ArrowRight steer, with steering responsive to speed; Space activates a temporary boost that raises the maximum speed and acceleration while a boost meter is available, and the meter slowly replenishes when not boosting. Keep the car constrained to the playable field; driving off the asphalt slows it down.

Place exactly 10 floating gold coin pickups along the racing line, alternating slightly inside and outside the center lane around the oval. Coins should visibly spin, bob up and down, and have a glowing ring; collecting one when the car is close hides it and increments the coin count with a small pickup tone. The objective is to collect all 10 coins and complete 2 laps before the 90-second timer expires. Count a lap only when the moving car crosses the finish area in the proper direction at sufficient speed, and prevent repeated counting while lingering at the line. Win when both requirements are met, displaying a large centered dark translucent message such as “You won the race! Press R to restart.” Also allow the alternate win wording “All coins collected — race won! Press R to restart.” If 90 seconds elapse first, stop gameplay and show “Time up! Press R to restart.” Pressing R reloads/restarts the game.

Add two moving rival cars on the oval, each following the track continuously in its own lane at different speeds. Colliding with a rival briefly reverses/slows the player and triggers a low bump sound, with a short collision cooldown. Add trackside hazards: many orange traffic cones lining both sides of the track and trees distributed around the grass outside the road, avoiding the road itself. Colliding with cones or trees similarly knocks back/slows the car and has a brief cooldown. Use Kenney car-kit race car, cone, and toy-car-kit gold coin/tree GLB assets when available, with simple geometric fallbacks if assets fail.

The HUD is fixed over the game: four rounded dark blue-gray translucent panels with white bold text across the top reading “Speed: 0” (display speed as the absolute vehicle speed scaled to an arcade-friendly value), “Coins: 0 / 10,” “Laps: 0 / 2,” and “Time: 01:30,” updating continuously. When the game ends, show a centered rounded dark translucent result panel. On desktop show a bottom-left help panel reading “W/S accelerate & brake · A/D or ←/→ steer · Space boosts · Collect 10 coins and finish 2 laps before time runs out.” On touch/mobile layouts, show large translucent on-screen controls: a four-button directional cluster at bottom-left with up, left, down, and right arrow buttons, plus a large bottom-right “BOOST / SPACE” button. Buttons should respond to pointer/touch hold and visually highlight while held. Make the interface responsive and prevent page scrolling.
