Thanks so much for bringing this to my attention! I was too busy with downloading at the last minute and just uploaded the exe and not a pkg file that was also needed to run the game. I've added a link to Dropbox for the working game as I can't upload new versions until the GMTK Jam voting period has ended (and will probably just have broken the rules of the jam by doing that, but it's fine 😊 ). Thanks again for taking the time to let me know!
