same here. I read your devlog about the game and thought I'd give it a try but no mac version. I'm pretty new to godot but my impression was it's fairly easy to cross publish. maybe that's not true in practice, but you should look into it.
Just let us know when and where we can test. You have at least two Mac users... ;)
I'm currently not testing my Windows binaries either, as I don't have a working Windows (virtual) machine anymore. The first Windows user will be automatically a sort of "beta tester"... ;p
We're all doing this as a hobby and at no payment at the end of the day... ;)
