You might need to upload your game to an external drive, so I can download it from there. I had the exact same problem with the secret URL for my game :( I hope they can fix it soon.
Yeah
I uploaded the game elsewhere
Mac - https://drive.google.com/open?id=1_-WYCwwpyU-G7YT7x2fOE2bvnkTIuJpE
PC - https://drive.google.com/open?id=1TFIg-iCCOWF-1GB5EkL1rAvubgQVzO6A
Let me know if it works.
