For those who are on Windows and are having trouble downloading the game, I believe you're downloading the wrong one.
You have to click "FTETheatrical-1.0-pc.zip" (Or FTETheatrical-Español-1.0-pc.zip for the Spanish version)
I made the mistake of clicking the Mac version, which of course, doesn't work. It'll also take some time to pop up, but it eventually does.
