ℹ️ This is the "official" solution to my Scratch Line Challenge project. You'll want to watch that first if you haven't already: https://scratch.mit.edu/projects/481705137/ Click the green flag and watch. If you want to skip a part (why would you want that?!) just click Champ99.
To learn more about SVG stroke attributes, look under S here: https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute I am also making a project with several SVG graphics with edited attributes, which can be used as a library sprite in the backpack so that you don't need to do the SVG "hacking" yourself: https://scratch.mit.edu/projects/484390740/ Thank you to all the participants, and especially to @pizzzapi and @kriblo, whose solution projects both educated me and inspired me to put way more effort into this solution project than I originally planned XD The Champ99 sprite is from the Scratch library. The mouse-click sounds were recorded by me.
