Hi.  Actually, the Downloads contain only the source code, so calling that a "Linux version" is a bit of a stretch by most Linux distributions as well ^^"

In theory, the novel should run on any machine you can get Guile-SDL2 (and subsequently Tsukundere) to run.  At the moment, the platforms on which this is known to succeed are Debian Testing i386 and amd64, Ubuntu Focal amd64 and GNU Guix x86_64¹.

Since you are querying for a version other than Linux, I assume you are little interested in Fedora or Arch, which are hitherto untested Linux distros.  I will also assume you're not running *BSD, the Hurd or any other OS with a comparatively minor market share, as you would have specified so in that case.  Which leaves us with the giants Microsoft and Apple.

For Microsoft "Win"dows, there are currently only some failure reports from which all I can deduce  is that existing guides need to be taken with a grain of salt.  Stuff you can try include MinGW, Cygwin, WSL, virtual machines and upgrading to Linux.

For the Apple OS, Homebrew should give you both a working Guile and SDL2 package², so you should be able to build Guile-SDL2 from that.  Only problem might be locating the shared library IIUC.

¹ This is equal to amd64 on Debian-based distros.  i386 probably works as well, but I only have my own machine plus the unknown thing CI builds on.

² I have not verified that it actually does.  Please don't hate me, Apple fanboys.
