I just get "The application “Dissonant Psyche” can’t be opened."
I've had the same issue with a number of games in this jam, does the Mac version work for you?

Good news! The issue was on my end. Turns out if the default Archive Utility on Mac unzips the file it doesn't work but if you use something else like The Unarchiver it works perfectly. (https://superuser.com/a/1474193)
