And after the redownload I get this:
sdl2-font-context: unavailable font family and style: Segoe UI Regular
Thanks for reporting this.
Unfortunately, I chose Segoe UI as the default font for the application on Windows because it's the default on that platform. I imagine that due to licensing, it's unavailable if you're running through Wine.
I'll make note of it, not just for making it configurable, but also falling back on something else, instead.
As per the defpackage-plus issue, likewise thank you for that report. I can't believe that one fell through the cracks, but I hadn't set up my ASDF systems with it as a dependency. I've fixed it in the source, but given that this is a game jam entry, I won't be updating it here.
