Nice work! I noticed an issue with the resolution though. If you compare the SVG version:

To the PixiJS version:

You'll notice that the SVG version is much crisper, while the PixiJS version is softer and more pixelated. This is even easier to see if you zoom in. The SVG version looks like HDTV, the PixiJS version looks like Atari 2600.

Any idea how to fix this?

For anyone who encounters the resolution problem I described, here is one way to improve it.

    let renderer = PIXI.autoDetectRenderer(width, height,
      {antialias: !0, transparent: !0, resolution: 3});
    renderer.autoResize = true;
    renderer.resize(width, height);
