Glowcoil

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 polished browser game titled "Glowcoil": a neon arcade Snake game played on a square 24x24 grid. Use a very dark navy-to-purple gradient playfield with subtle blue glowing grid lines, a thin cyan border, rounded corners, and a soft cyan/purple outer glow. The game should be centered in a dark full-screen page and scale responsively, with the board sized to about min(94vw, 78dvh, 760px). Keep a HUD around/above the board: at top left show the spaced, bold glowing cyan brand text "GLOWCOIL"; at top right show two dark translucent rounded statistic pills labeled SCORE and SPEED, with large white values initially 0 and 1.0x.

At launch, show a centered modal overlay over the board. It is a rounded dark indigo/purple panel with a thin translucent cyan border, cyan outer glow and a subtle magenta inner glow. Display a large white "GLOWCOIL" heading with pink and violet neon text shadows, then the exact instructional copy: "Eat the energy cells. Grow longer. Move faster. Don't hit your own trail." Add a pill-shaped START RUN button with a left-to-right turquoise-to-violet gradient, dark bold text, and cyan glow. Clicking it begins the run and hides the overlay.

The player is a glowing segmented snake/coil. On reset, initialize four circular cells in a horizontal line around grid coordinates (12,13), (11,13), (10,13), (9,13), with the head moving right. Render each grid cell as a soft glowing circle centered in its grid square: the head is larger and bright mint/cyan (#72fff0), while the body uses teal/aqua hues that gradually shift toward blue-green. Give the head two small dark eyes positioned according to its current direction. Place one collectible energy cell at a random unoccupied grid coordinate; render it as a pulsing hot pink/magenta glowing circle with a tiny white highlight. The snake advances one grid square at a time, initially every 150ms. On collecting the energy cell, increase score by one, grow by retaining the added segment, spawn another energy cell at a random unoccupied square, and increase movement speed: step interval is max(52ms, 150 - score*4.2), with the HUD speed shown as (150 / interval) rounded to one decimal followed by "x". The initial speed is 1.0x.

Use classic Snake rules: the player can turn up/down/left/right, but reject a direct 180-degree reversal relative to the current direction. End the run if the head goes outside the 24x24 grid or collides with any segment of its own trail. On game over, stop movement, save the highest score locally under a best-score value, and show the modal again with title "TRAIL LOST", message formatted as "Score [score] · Best [best]<br>It gets faster every time you grow.", and button text "RUN IT BACK". Clicking it resets the snake and starts a fresh run. Space should also restart when not running.

Support keyboard controls with ArrowUp/Down/Left/Right and W/A/S/D. Support touch/mobile controls: on coarse pointers or narrow screens display a glowing four-button D-pad near the bottom of the screen with up, left, down, and right arrow buttons; clicking a button changes direction. Also allow swipe direction input on the canvas, using the dominant horizontal or vertical swipe axis and ignoring very short swipes. The canvas should prevent touch scrolling. Keep the visual style clean, futuristic, high-contrast, and neon, with no scenery beyond the grid, snake, energy cell, HUD, and modal.
