Hi there! I am sorry to hear you're having an issue with the application. It was built to be compatible with Mac so I am not sure why you are running into this problem.
I would first try uninstalling and reinstalling the software. Likely the app somehow got corrupted when you downloaded it the first time. Unfortunately there is not much else I can suggest, however if this doesn't work please feel free to request a refund through itch.io support. Here's a link where you can find more information on how to do that.

I apologize for the inconvenience, and sincerely hope you are able to enjoy the game.
Thanks, have a great day!
