Pixel Reveal resolves your word out of coarse blocks, the letters flickering between states as the resolution climbs — the look of a sprite loading on hardware that is thinking about it.
px-in steps the block size down in discrete jumps rather than interpolating smoothly, because real low-resolution displays have no in-between states. px-flick fires during the transition so intermediate frames read as uncertainty rather than a blur.
Yes — export at a resolution that is a clean multiple of the block size and the edges stay hard. SVG keeps them exact at any scale.
