Neon Coil

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 game titled “Neon Coil,” a polished neon 3D Snake game viewed from directly overhead in an orthographic camera. The playfield is a square 24-by-24 grid on a very dark navy/black floor, with faint glowing blue grid lines and subtle distance fog. Use a Three.js-style scene with a top-down camera and soft cool lighting. The snake is made from chunky small 3D rectangular/cuboid segments sitting just above the floor, glowing cyan/electric blue; the head is slightly larger than the body, and the body shifts through cyan, blue, and violet/pink hues along its length with emissive neon shading. At the beginning, place a four-segment snake near the center, facing right. The collectible is a rotating low-poly/chocolate cake 3D model on the grid, positioned at a random unoccupied cell; it should visibly rotate and gently bob/tilt. The goal is to steer the snake into cakes: each cake increases the score, adds one segment, spawns another cake at a random cell not occupied by the snake, and increases movement speed by 0.075x, starting at 1.0x. The snake advances automatically on a discrete grid: its initial movement interval is about 0.16 seconds and becomes faster with score, capped at a minimum interval of about 0.055 seconds. Do not allow an immediate 180-degree turn. The run ends if the head leaves the 24-by-24 board or collides with any segment of its own body. On game over, stop movement and show a centered overlay reading “SIGNAL LOST” with a message such as “The snake ate N cakes.” and a “RUN IT BACK” restart button. Persist and display the best score using browser local storage.

Build a full-screen responsive interface over the canvas. At the top left show the glowing cyan brand “NEON COIL.” At the top right show SCORE with a prominent current number, then BEST and SPEED (formatted like 1.0x). The initial centered modal has a dark translucent panel with rounded corners, a thin cyan border, cyan/purple glow, the large magenta neon title “NEON COIL,” explanatory text “Eat the chocolate cake. Every slice makes the snake longer — and faster.”, a pill-shaped cyan-to-lime “START RUN” button, and a small hint “Arrow keys / WASD · swipe or tap the pad.” Hide this start overlay once play begins. Provide keyboard controls using Arrow keys and WASD, and touch controls on mobile: a four-button directional pad with up centered above left/down/right, translucent dark-blue buttons with cyan borders and arrow glyphs. Also support swipe gestures on the canvas. Keep touch controls visible on touch/mobile layouts and hide them on larger fine-pointer desktop layouts. Use a dark cyberpunk arcade visual style with cyan, electric blue, violet, and hot pink emissive accents, clean system sans-serif typography, responsive safe-area spacing, and no extra mechanics beyond those described.
