Ah damn. Sorry, I don't have a mac to test it on. Can you play the web builds?
Ah, thanks, yeah, that's probably related to Apple's new requirement that every developer pays them a fee to sign their app. I'm... not going to do that for a free game :)
Instead of downloading the game though, can you just hit the play button on this page and play the game in your browser?
