MATHREE TO NGANYA

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.

Rebuild a lightweight browser-based 3D first-person driving game titled “MATHREE TO NGANYA · NAIROBI.” Use Three.js or an equivalent low-poly WebGL renderer with no lighting or shadows, flat solid-color materials, antialiasing off, a muted gray-green background, and fog that fades the distant road and scenery. The player is driving a Nairobi matatu on a compact straight road that loops by wrapping the vehicle’s position from one end to the other. The camera is seated inside the vehicle behind the dashboard, looking through a dark translucent windshield framed by red pillars; show a red interior roof edge, black dashboard, yellow dashboard trim, a black steering wheel with a yellow hub at the lower left, a rear-view mirror, several small dashboard gauges, and a blue livery strip near the windshield. Include a simple low-poly conductor/makanga standing by the passenger side, visible when looking right, made from cylinders/boxes with dark legs, a teal shirt, and brown skin-colored head and hand.

Build the world as a narrow eight-unit-wide dark charcoal road extending roughly 150 units along the depth axis, bordered by thin yellow edge lines and regularly spaced short yellow center lane marks. Put the road over a broad flat green grass plane. Along both sides, sparsely place alternating low-poly Nairobi/Eastlands-style shop blocks: simple brown/orange rectangular buildings with dark brown flat roofs and small red or yellow signs. Add a few simple trees made from brown trunks and faceted green canopies. Populate the route with exactly four reusable low-poly traffic vehicles, alternating red and blue bodies with cream roofs, traveling slowly along the route, and five reusable pedestrians on the roadside, represented by simple low-poly silhouettes with dark legs, teal/blue shirts, and brown heads. Do not add extra spawning systems, weapons, enemies, damage, scoring, or missions: the implemented activity is simply driving the looping route, controlling speed and steering while observing the surroundings.

Driving behavior: begin stopped at the center of the road. W/Up accelerates toward a maximum target speed of 10 world units per second; S/Down brakes and can stop; with no throttle the speed eases down gradually. A/D or Left/Right smoothly steer, changing yaw based on current speed, while constrain the vehicle’s lateral position to approximately -2.4 through 2.4 so it stays on the road. Move forward along the route and wrap from z=72 to z=-72 and vice versa. Add a subtle camera bob while moving. Mouse movement controls first-person view yaw and slight vertical look after pointer lock; clicking the canvas requests pointer lock. Press Space to sound the horn and display a temporary “HORN!” message. Start with a button click that hides the start screen, requests pointer lock, starts quiet looping background audio if permitted, and displays the greeting “Umoja, Umoja, ingia ingia!” The game should periodically display one of these makanga callouts for about 1.8 seconds: “Umoja, Umoja, ingia ingia!”, “Kayole, Kayole, kuna space!”, or “Tao, tao, mwisho wa gari!”.

Overlay HUD: render HTML UI over the canvas. At the top left show “MATHREE TO NGANYA · NAIROBI.” At the top right show live speed in km/h, calculated by multiplying the world speed by 3.6, initially “0 km/h,” and beneath it “ROUTE 33 · LOOP.” At the upper center show temporary callout text in pale yellow inside a dark translucent box with a yellow border. Along the bottom center show “WASD drive · mouse look · Space horn · keep left.” On coarse/touch screens replace that hint with two on-screen control pads: a circular-style directional pad for forward, left, horn, and right, plus a separate down/brake button, wired to the same controls. Use a dark teal/charcoal start overlay covering the screen; center a card with a dark gray-green background, thin yellow border, rounded corners, and shadow. The card title is yellow “MATHREE TO NGANYA,” followed by the exact description “A lightweight first-person Nairobi matatu drive. Ease out, hold your lane, and listen for the makanga calling stops.” and a red-orange “START ROUTE” button. Keep the visual style compact, arcade-like, functional, and performance-conscious, with the scene visible behind the translucent UI only after starting.
