Ack, we are so sorry to hear that. I'll contact our MAC testers to see if they can do a quick run of this, but if you have time, if you could please send us an email at gamesravenstar@gmail.com with your MAC's specifications, and any screenshots of what is happening (nothing happening seems to be the problem, but just in case there's any message anywhere) we'd be super grateful. In the meantime, I'd reccommend trying the Steam version if you want to, as Steam fortunately doesn't have any problem with MAC versions of the game.
Sadly this is a frequent problem with Apple and itch.io, it seems ;_;! I'll update you all as soon as we find a solution!
