Hey Yeh33!
This is most likely an issue with the servers on Itch, which is unfortunately out of our control.
You could try grabbing it from our Patreon where we have a few mirror sites to download from, and, we also have both the high-res and compressed version there. Here's a link to the latest free version:
It requires a Patreon account, but free to create if you don't have one already.
Hope this helps!
