50CC Life

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 arcade motorcycle-driving game titled “50CC Life” / “50CC Life Simulator,” presented in a clean low-poly Three.js-like style. Use a third-person chase camera behind and slightly above a small 50cc supermoto, with an optional first-person camera toggle. The setting is a sunny French-town test zone: pale blue sky with light fog, green grass, a long dark charcoal asphalt road with a dashed cream center line, side roads/intersections, pale curbs, simple colorful box-shaped houses with dark roofs, doors and blue windows, a garage building, a roadside sign, and several orange/white traffic cones. Keep the world simple and spacious, with soft shadows, ambient daylight, and a semi-realistic low-poly presentation.

The player rides a detailed original compact street 50cc motorcycle. Model it from visible mechanical parts rather than a generic vehicle: two black tires with metallic hubs/rims, a metallic tubular frame, dark AM6-style engine, cylinder head, visible 16 mm orange carburetor, chain and sprockets, low orange exhaust/muffler, red front and side bodywork, dark seat, chrome handlebars with black grips, cream headlight, foot pegs, and visible suspension/frame details. Place the bike on the road and keep it centered within a narrow driving corridor, allowing lateral movement only across the road width. The chase camera follows smoothly and looks toward the motorcycle; the alternate first-person view sits around rider/handlebar height and looks forward.

Core gameplay is open-road riding rather than racing or combat. Accelerate with W or Up Arrow, brake/reverse decelerate with Space or Down Arrow, and steer with A/D or Left/Right. Steering changes heading and moves the bike, with speed capped and the bike constrained to the road; when reaching the end of the straight route, wrap the motorcycle around to the other end so the route can be ridden continuously. With no throttle, gradually slow down. Support six forward gear steps plus neutral: Q shifts down, E shifts up, and display N at neutral. Engine RPM should rise with speed and selected gear, starting at 1200 rpm. Add a subtle engine sound whose pitch follows RPM and whose volume increases with speed after user interaction.

Show a prominent translucent dark HUD with rounded corners and a modern white/orange design. At top left display “50CC LIFE / MONTLUÇON SLICE,” with LIFE highlighted orange. At top right show a large speed readout in km/h, then current gear, RPM, and money; initialize at 0 km/h, N, 1200 rpm, and €420. Under it show the fixed specification text “AM6 street · carburateur 16 mm.” At lower left show driving help: WASD/arrows to drive, Space to brake, Q/E for gears, V for camera, and G for garage. At lower right show “ROUTE OUVERTE · JOUR 08:42.”

Implement a garage customization overlay toggled by G or a visible GARAGE button. Opening the garage pauses riding. The panel is labeled “GARAGE — MRT STREET” and explains that parts can be installed and observed immediately. Include a toggle for the engine kit between “50cc origine” and “Top Rose 75cc”; the upgraded kit costs €180, reduces money accordingly, and increases acceleration and top speed compared with the original. Include a cosmetic color selector with red (default), blue, off-white, and dark charcoal swatches that immediately recolors the motorcycle’s red body panels. Include an exhaust toggle labeled “Passage bas” / “Passage haut” (it may update the selected part label and appearance), plus a “Reprendre la route” button to close the garage. On small/touch screens, provide large on-screen controls for left, throttle, right, brake, and GARAGE, while desktop users use the keyboard. Use responsive translucent panels, rounded buttons, and readable white text; do not add enemies, traffic, weapons, races, lives, or other systems not described here.
