Building a browser game based on KiCad

I've been making boards in KiCad for a while now. I really enjoy figuring out how to route all the components in the PCB editor, especially the weird "hard" things like differential high speed signals. I'm probably not very good at it but so far the margins for the stuff I'm designing is wide enough that it works anyway. Every time I'm working on this I feel like this would make a neat puzzle…
