Yes, I also forgot to add that I'm using windows 11. Now that I've written it and noticed you don't have a windows version for PC.
There is a windows version, it was just marked wrong!
I tried again, and I think the screenshot speaks for itself.
Unfortunately, I'm unsure what the issue is, as it appears to be something with itch. Have you tried another browser? As I've just downloaded the file myself without issue
I tried it with Microsoft Edge and that worked.
Excellent! Glad it worked :)
