Looks like there is an issue with the Mac build. There's no app there, but what looks like some source files. If you manage to get a Mac or Web build I'd be happy to check it out.
Thank you for pointing this out to me! Ill see if the Admins would let me to reupload the Mac download at least. Apparently I dun' goofed when trying to export the project for Mac, and didn't even notice untill now!
And it should be fixed now! Sadly I don't have access to Mac to see if it works myself, but the Mac download is now updated and should be (hopefully) working!
Unfortunately, it's just opening to a blank screen with music, so something must be off. Let me know if you're able to figure it out, and I can try again.
