I can't download this via Itch.io

Can you elaborate? What happens when you try to download it? And are you download via the browser or the app?

I'm trying to download it via the itch.io app.  It constantly cycles through the "Computing space requirements" message and won't allow me to click the Install button. 

Don't know it's an issue on my end but I have enough space to download, and most install for other games go fine.

Very strange, I'm not sure what's happening since it seems to be working fine for me. You can try downloading and installing manually without using the itch app from https://cosmoteer.net/. If that works for you, then that would indicate it's specifically a problem with the itch app that I can't do anything about, and Itch support might be able to help.
