Having the same issue as this guy: https://itch.io/t/367976/601-will-not-start-on-mac - just with the 2 most recent versions.
Can I please get a refund?
NO WAY! I'm so glad you got it fixed! Thanks for following up here, by the way: it's good to know what caused this so that if it happens again I can tell that person "um hey look it's almost definitely the read privileges".
Hope you like the game now you've finally got it working! :)
