← Snake, with one idea of your own · play what it built · pi's own transcript

system preamble (from the harness)
You are building a self-contained static demo that will be published to a static host and
opened directly in a browser. Non-negotiable constraints:
- Vanilla HTML, CSS and JavaScript only. No build step, no bundler, no package manager, no
  framework, no server-side code, no TypeScript that needs compiling.
- Everything lives in the current directory. `index.html` is the entry point unless the task
  says otherwise.
- It must work completely offline. No CDN links, no external fonts, no remote images, no
  network requests of any kind. Draw or generate any graphics you need (CSS, SVG, canvas,
  inline data URIs), or do without.
- Write files with the write tool. If a file is getting long, write it in chunks (write the
  first part, then append with edit) — a single oversized write can be truncated silently.
- Before you finish, read back the files you wrote and confirm they are complete and
  consistent. Do not leave any background process running.
Finish the whole task. A partially built page that stops halfway is worse than a smaller
one that is complete.
the prompt (identical for every model)
Build a playable Snake game that runs from `index.html`, and add **exactly one original
mechanic of your own design** on top of it.

## The Snake part (fixed, so every version is comparable)

- A 24×24 grid rendered on a canvas, roughly 720×720 CSS pixels.
- Arrow keys and WASD both steer. The snake cannot reverse directly into itself.
- Eating food grows the snake by one segment and scores a point. New food never appears on the
  snake.
- Hitting a wall or yourself ends the game. A game-over state shows the score and restarts on a
  keypress, fully resetting everything.
- The snake moves on a fixed tick (start around 8 steps per second) that speeds up slowly as it
  grows, with a floor on the tick length.
- Score and high score are visible; the high score persists across reloads via `localStorage`.
- Pause on **P** or **Escape**.

## The twist (yours)

Invent **one** mechanic that changes how the game is played — not a cosmetic effect. It should
be simple enough to explain in a sentence and should create a real decision for the player,
ideally a trade-off. Then:

- Make it work properly, including its interaction with growing, dying and restarting.
- Give it a name.
- Print the name and its one-sentence explanation on the page, under the board, so a player
  knows the rule before they start.

Do not add a second twist. One idea, done well, is the task.

## Requirements

- Everything drawn with canvas or CSS — no images, no network.
- The tick loop must not drift or speed up on faster displays.
- Keys used by the game must not scroll the page.
- Show the controls on the page.

Make it feel good to play: readable at a glance, responsive input, an obvious moment of
feedback when you eat something.

    The playable Snake game has been implemented in index.html. ### The Twist: Chrono-Fruit I have added a mechanic called **Chrono-Fruit**. - **The Mechanic**: Occasionally, a blue fruit appears on the grid. Eating it slows down the game's tick rate by 50% for 5 seconds, giving the player more reaction time. - **The Trade-off**: Unlike regular red fruit, the Chrono-Fruit provides **no score** and **no length increase**. The player must decide whether to detour for the safety of slower speed or continue pursuing a high score. ### Implementation Details: - **Grid**: 24×24 canvas, 720×720 pixels. - **Controls**: Arrow keys and WASD for steering; P or Escape to pause. - **Speed**: Starts at 8 steps/sec, increasing as the snake grows, with a hard floor of 20 steps/sec. - **Persistence**: High score is saved via localStorage. - **Self-contained**: No external assets or libraries used; all graphics are rendered via Canvas API. - **Game Loop**: Uses requestAnimationFrame with a delta-time calculation to ensure the tick rate is consistent regardless of display refresh rate.
