I don't really want to admit my crappy test linux environment ;p
Debian bullseye linux container on an amd64 chromebook.
In general sdl2 works fine for me in my common lisp ffi .. Is it possible I did something really wrong with chicken-install ?
The *game* works fine- there's a long, black load time but then, despite the messed up graphics I can move around with wsad and the charges get attracted as expected (and I die when I hit the edge)
