Space Shooter

Long prompt.  Got cut off!!

I use bullet points in my prompts because too much information on one line uses up the tokens and the LLM skips a lot. Every single thing on a separate line makes a huge difference.

create a complete, single-file html5 canvas game titled "space shooter" with embedded css and javascript. no external libraries except google fonts. 

IMPORTANT!! follow these exact specifications. Do not skip a line. Constantly read this prompt again until the code is done:

architecture requirements:
- output as one self-contained .html file with <style> and <script> tags.
- use requestanimationframe with delta-time (dt) physics.
- dynamically resize canvas to window.innerwidth/height on load and resize event.
- save high scores to localstorage under key spaceshooterscores.
- block default right-click context menu on canvas.
- use canvas 2d api for all rendering (no dom/svg overlays for gameplay).

visual style:
- aesthetic: 1980s color vector arcade style. neon glowing lines using ctx.shadowblur and ctx.shadowcolor.
- fonts: import oxanium (200-800) for gameplay ui and audiowide for menus/title screens via google fonts. scale all in-game text by 1.5x base size. menu text uses audiowide.
- background: black screen. white 1-pixel parallax stars scroll opposite to camera movement. stars wrap seamlessly.
vector rendering: all ships, asteroids, weapons, and ui elements drawn with ctx.stroke() or ctx.arc(). no sprites or images.

screen flow & navigation:
- attract screen: title "space shooter" (audiowide), subtitle "generic space shooter", blinking "press any key to play". parallax stars animate upward.
- controls screen: lists all controls & power-up icons with vector graphics next to names. increased line spacing (40px per line).
- high scores screen: top 10 scores from localstorage, 3-char names, score values. "press any key to play" prompt.
- screens 1-3 auto-cycle every 10 seconds.
- play screen: main game view.
- name entry screen: overlay on game. blinking cursor. a-z input, max 3 chars. enter to submit, esc to return to high scores.

shop screen: 
- between levels. lists purchasable power-ups with vector icons. ↑/↓ to select, enter to buy, space to continue. shows "not enough gold" or purchase confirmation.

player mechanics:
- ship shape: enterprise-style vector outline (saucer, hull, wings, bridge).

controls:
- w or up = thrust forward
- a & d or left and right= rotate
- s or middle mouse = activate shields
- left click = fire bullets
- right click = fire phaser beam
- space = fire active special weapon
- scroll wheel = cycle special weapons (torpedo → mine → homing)
- pause: p key toggles pause overlay with "paused", "p: resume", "q: quit to title".
- quit: q key instantly returns to attract screen, clears active sounds.

physics: 
- frictionless newtonian drift. velocity cap: 600 px/s. acceleration: 200. max thrust: 600.

shields:
- 10 units max. each hit reduces by 1. if shields > 0, no damage taken. ship flashes red on hit. color shifts from cyan/green → red as shields deplete.

lives:
- start with 3. on 0 shields, ship explodes , loses all power-ups, respawns in 3s. 
- if killed by black hole, respawns at random safe location. game over at 0 lives.

thruster audio:
- continuous white noise
- frequency scales with thrust level. stops smoothly when thrust ends.

play area: 
- 5x screen width/height. camera smoothly follows player

boundaries:
- objects bounce off edges with velocity reversal (omega race style).

black hole:
- center of map. kill radius: 24px. 

gravity constant:
- affects player, enemies, asteroids, and all projectiles.

time dilation:
- as player approaches black hole (<700px), global time scale reduces to 0.25x linearly. all game updates multiply by dt * timescale.
- ghosting effect: within 900px of black hole, all entities render 5x trailing ghosts. trail skip distance increases closer to center. ghost opacity scales with proximity.
