A couple of people reported having trouble downloading the Mac version. From what they told me, they were able to resolve the issue by using a different browser. For some reason, Safari wasn't completing the download. It was probably due to the larger file size. Could that be the case for you?

Let's run a test to see if the problem is with the file, the website where it's hosted, or a restriction on your computer.
I've uploaded the PC version of the game to this Google Drive link:

Try downloading it from here and let's see what happens.
