Maybe I can test the build on my Mac if you want? I'd be glad to help! Oh and... really, this is a great game, the short stories are also perfect. I read them all in one session haha! Congratulations again, and I'm here to help.
Oh wait, is the update the new build that has working saves on itch?
Edit:
Oh hey again, I updated the game and now I can't launch it. Nor from Itch nor from the folder, seems like a problem with the .jar. Let me know if I can be of more help. Tried unistalliing/erasing the game and re installing it too.
