Interesting icon set. I love the idea behind it, but looking at their icon preview at https://i0.wp.com/codefisher.org/wp-content/uploads/2022/08/..., I noticed that some images look great at higher resolutions (the star), while others look like a bad hqx/xbrz job, with a mix of curved, pixel-aligned (lock, book, anchor, monitor stand), and blurred features (book stripes), with inconsistent line widths (the house's roof and bushes, the computer stand and anchor).
