unless i am being very stupid, which is extremely likely, the mac version doesn't have any kind of executable file included?

… YEAH. DANGIT. 

Arc here. I do not own a mac and thus couldn’t verify that file. City is the mac-daddy so they are building the distro. Check again in like ten minutes and it’ll be fixed.

Sorry. Something had to hiccup, didn’t it?

EDIT: The file should be fixed now, please re-download it for the right version! This was mostly my bad, sorry about the inconvenience, but please enjoy the game once you are able to redownload~! -city
