## Changes

Modified by Invisible Network on 2026-10-17:

- Removed files the game does not need, or that only served removed features: `.github/FUNDING.yml`, `.gitignore`, `CNAME`, `README.md`, `a.js` (an empty file), `manifest.webmanifest` and the icons only it used (`images/icons/maskable-*`, `images/icons/transparent-*`, `images/icons/apple-touch.svg`), the share and app-store images (`images/android.png`, `images/appstore.svg`, `images/btn_facebook.svg`, `images/btn_twitter.svg`, `images/btn_share.svg`, `images/facebook-opengraph.png`, `images/twitter-opengraph.png`), the unused `images/icon_arrows.svg`, the social-share library (`vendor/rrssb.min.js`, `style/rrssb.css`), the unminified `style/fa/css/font-awesome.css` (the page loads the `.min.css`), and the unused fonts `style/fonts/Lovelo.otf`, `style/fonts/QuattrocentoSans-Regular.ttf` and `style/fonts/roboto.woff`.
- `index.html`: removed the web-app manifest link, the iOS Smart App Banner meta tag (`apple-itunes-app`), the Google Fonts stylesheet (the bundled Exo 2 fonts in `style/style.css` are used instead), the Google AdSense script, the inline Google Analytics script, the "SHARE MY SCORE!" Twitter button, the Facebook/Twitter share buttons and the App Store and Google Play badges on the game-over screen, the script that added a VK share button for Russian-language browsers, and the `rrssb` stylesheet and script. The `#buttonCont` element is kept, empty, because `js/main.js` uses its position to lay out the game-over screen. The Open Graph and Twitter-card `<meta>` tags are unchanged; browsers do not fetch anything for them.
- `js/main.js`: removed the request that sent each final score to `http://54.183.184.126/`, and the code that loaded a remote script from `http://hextris.io/a.js`. In the help text, removed the "Find Hextris on iOS & Android" app-store links. The author credit links and the "Hextris Website" link are kept and now carry `rel='noopener'`.
- `js/initialization.js`: removed the Google Analytics loader and its `ga()` calls.
- `js/view.js`: the pause screen no longer shows the "ad-free version" app-store and website links. All three platform variants of the pause message now show only "Game Paused".

No other file was changed.
