Here's some code to add a old CRT monitor effect over your HTML-published carts.

I read an article recently about how low-res graphics looked better/softer on old CRT monitors and TVs, so did some googleing and found an effect you can apply via Cascading Style Sheets to your HTML-published game.

When you've export my_game.html open up the .html file in a text editor and add the following inside a STYLE tag near the top of the file:

  @keyframes flicker {
  0% {
    opacity: 0.27861;
  }
  5% {
    opacity: 0.34769;
  }
  10% {
    opacity: 0.23604;
  }
  15% {
    opacity: 0.90626;
  }
  20% {
    opacity: 0.18128;
  }
  25% {
    opacity: 0.83891;
  }
  30% {
    opacity: 0.65583;
  }
  35% {
    opacity: 0.67807;
  }
  40% {
    opacity: 0.26559;
  }
  45% {
    opacity: 0.84693;
  }
  50% {
