I don’t know enough about the underlying code (I am the guy who still makes jokes about how html is super easy before remembering that it has been 30 years since I made websites with frames…) but yeah. HTLM5+Javascript with a heavy reliance on Impact support libraries.

The end result is that it is a god damned shitshow to get running on modern platforms and controller support is an even bigger mess. Like, I STILL don’t entirely understand how it manages to detect the difference between an xinput device and a device Steam is binding to xinput… on Linux via Proton. And it tends to break for anything but a proper microsoft made xinput device…
