I've now realized I don't have any way to playtest a Mac or Linux version of the game. If you'd like me to build a Linux version for you, I can go ahead and build it, but I can't guarantee that it'd even work. ¯\_(ツ)_/¯
If it's not a big effort for you, I'd be happy to test it.
I just uploaded a Linux build of the game. Here's hoping it works!
I tested it, and the Linux version runs perfectly.
woohoo!
