Street Heat

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-based 3D arcade driving game titled “Street Heat,” subtitled “A city run after dark.” Use Three.js or an equivalent real-time 3D engine with a third-person chase camera behind and above the player car. The scene is a dark, low-poly/blocky city at night: use a deep blue-black background with fog, a large flat ground plane, a grid of broad dark gray roads/lane strips, small green curb/median blocks, and many simple box-shaped buildings arranged around the streets. Buildings should be chunky rectangular towers in muted blue, purple, gray, and brown tones, with soft dramatic nighttime lighting: cool blue ambient/fill light and warm directional light, shadows, and subtle atmospheric fog. Keep the visual style minimalist and geometric rather than detailed or realistic.

The player is a small sports sedan/car placed near the center of the city. Drive it with WASD or arrow keys: W/Up accelerates forward, S/Down brakes/reverses, A/Left and D/Right steer. Steering changes the car’s heading and movement follows its facing direction. Add touch controls for mobile: circular left and right buttons on the lower left, circular brake/down and gas/up buttons on the lower right, plus a rectangular NITRO button. Holding Shift (either Shift key) or the NITRO button activates nitro, but nitro only boosts while accelerating. Normal speed is capped around 16, nitro speed around 24; allow reverse down to about -6. Keep the vehicle within a square city boundary roughly 31 units from the origin.

Place exactly six glowing, rotating golden cash crates around the city at these approximate world positions: (-16, 0.45, 0), (16, 0.45, 0), (0, 0.45, -16), (0, 0.45, 16), (-24, 0.45, -16), and (24, 0.45, 16). They should visibly glow and gently bob/rotate. When the car comes within approximately 1.6 units of a visible crate, collect it: hide the crate, add 100 to CASH, add 6 seconds to TIME up to a maximum of 60, and increase HEAT by 1 up to a maximum of 5. There are no enemies, weapons, traffic, or other obstacles beyond the city geometry and boundaries.

Start each run with TIME 60, CASH 0, HEAT 0, the car stopped near (0, 0.18, 11), and heading forward. Count time down continuously in seconds while playing; when it reaches zero, clamp it to zero and stop gameplay movement/collection. Resetting/restarting should restore the timer, counters, car position, heading, speed, and all six crates. Do not invent a win screen or complex game-over screen if none is specified; the essential end state is that the timer reaches zero and the game stops responding to driving logic.

Overlay a fixed glassy dark HUD on top of the 3D view. In the upper left show a rounded card with large uppercase “STREET HEAT” and the smaller blue-gray subtitle “A city run after dark.” In the upper right show a rounded stats card with “TIME” and its value, “CASH” and its value, and “HEAT” and its value. At the bottom center show the instruction text: “WASD / arrows to drive • Shift for nitro • collect the glowing cash crates.” Use white/light-blue text, translucent navy-black panels, thin pale borders, rounded corners, and subtle shadow/blur. Keep the touch buttons visible over the lower portion of the screen, with translucent dark circular buttons and white arrow glyphs; the NITRO control is a wider rounded rectangle labeled NITRO. Make the chase camera smoothly follow behind the car and look toward a point slightly above it, with a perspective view that clearly shows the road, nearby block buildings, and glowing pickups.
