The OSX bundle that is available seems to be a "Mach-O 64-bit executable arm64" which I guess means that it is only for the new M1 and M2 Macs. Will there be a version available that can run on the older Intel based Macs?

Ah, I figured out that the game is super playable on Intel Macs if I download the Windows version and play it with Porting Kit :-)
