The artist's website abuses the "click a link" clacking sound on a webpage. The entire comic is loaded and scrolls between panels. However for the jumpscare(s), it shudders and audibly clacks as it "rapidly clicks hyperlinks" to jump between frames. It's really neat effect and startling as shit. This page just hosts the comic. To confirm, in this link, you can not click between frames and just scroll with tye mouse ob the scrollbar down the right side.
