What did you build this in? If possible I recommend making it browser playable, it seems here on itch almost no one will give your game a chance if they have to download it. (We live in days of instant gratification only.)
It was built in Unity, so browser playable is possible and I should definitely look into it, thank you for the suggestion. Also, I've looked into the issue you had and I also experienced the same using a Mac. I'm guessing it's because unlike previous times I've made a Mac build, this one I made on my Windows computer, lesson learned. I hope to be able to upload a proper working Mac build within 24 hours, thank you for your patience and helping me find this issue.
