Changes made for this site
Original: https://github.com/jackrugile/radius-raid-js13k @ 361ab5166570cfc8a29a4fc15c9afba566117b66 (MIT, see LICENSE.md)

- Copied only runtime files (index.html, js/) plus LICENSE.md. The minified build (min.html, min.zip) and README were not copied.
- js/jsfxr.js is JSFXR by Markus Neubrand (https://github.com/mneubrand/jsfxr, Apache-2.0); its license text was added
  as LICENSE-jsfxr.txt (from commit b2bfe50fddc7e281e1c1944870071b2ccd2c0440). The file itself is unchanged.
- index.html: added charset/viewport meta tags; body gets margin 0 and overflow hidden.
- js/game.js: the fixed 820x620 game frame is now scaled with a CSS transform to fit the window/iframe
  ($.resizecb), and mouse coordinates are divided by that scale so aiming stays accurate ($.mousescreen).
- js/game.js: removed the "JS13KGAMES" button on the credits screen (it navigated away to an external site);
  the MENU button moved to its position. All in-game credit text is unchanged.
- js/audio.js: play() promise rejections (browser autoplay policy before the first click) are now caught.
No gameplay logic was changed.
