Oh I see. I just checked the game on my Mac, which is running on an M1 MacOS 11.3.1, and it appears to patch and install well from the file version currently on itch.io. Since the build of the Launcher was made in 2020 on MacOS 10.14 and has been working fine with all MacOS since then, I don't believe it is an issue with the code/game, but perhaps an issue with a Firewall or protection system on your end, either software (on your computer) or on the network level.
I am more than happy to troubleshoot this with you further, even walking you through how to manually patch the game, if you would like to chat in Discord. You can find me at our discord.gg/phanxgames
Thank you for your interest in the game,
Henry
