This game is excellent , I look forward to seeing its final form.!
However does it only save progress (after exiting ) in the mobile version?
I also can't get it to work on my Mac, when opening on it I get this:
I also got a warning about this game being 32 bit and not 64 bit but I clicked through that without reading closely, assuming I could set it to run at 32 bit if that was problem. Alas that's not a thing you can do since the latest update.
So I hope that's not the problem.
