Shadow Fight Arena

About

Shadow Fight Arena turns any webpage into a 1v1 silhouette combat arena.
Two players, one keyboard, infinite battlegrounds.

HOW IT WORKS
1. Hit the extension icon (or Cmd+Shift+Y / Ctrl+Shift+Y) on any page.
2. The page dims and a combat overlay drops in. Every heading, paragraph,
   image, button and link becomes a physics-enabled platform.
3. CAPTURE PHASE (60 seconds): both fighters scramble across the page,
   absorbing DOM elements as weapons. Long paragraphs become swords. Images
   become rocket launchers. Short text becomes throwable kunai.
4. COMBAT PHASE (4 minutes): pure fighting. Melee, ranged, dashes, parries,
   double-jumps.
5. K.O. wins. Toggle off, page returns to normal.

CONTROLS
Player 1: WASD to move/jump/crouch, F/G to light/heavy attack, R parry,
Q dash, E hold to grab weapons.
Player 2: Arrow keys to move/jump/crouch, K/L to attack, Shift parry,
'/' dash, ';' hold to grab.
Press H any time to toggle the in-game controls panel.

PRIVACY
Shadow Fight Arena makes ZERO network requests. It does not collect,
transmit, store, or share any user data of any kind. Everything stays
local to your browser. Toggle the extension off and the page returns to
its untouched original state.

REQUIREMENTS
- Chrome 102 or newer
- Works on any HTTP/HTTPS page (won't activate on chrome://, file://,
  or extension-store pages by design)

Made with vanilla JavaScript, HTML5 Canvas 2D, and zero npm dependencies.
