This is just a short post to say that I've added a version of Moirai for OSX. It requires OSX 10.7(Lion) or higher. Unfortunately XCode 5 on Mavericks wouldn't allow me to build it for anything older than that. You can download it here.
I've also updated the Windows versions with some minor bug fixes that were reported.
In a bit less than two weeks I'll post up an article summarising the responses to the game and some interesting observations from our end.
