Just thought I'd bring this up, as I don't know if anyone else is experiencing the same issue.
I am unable to download the game using the Windows itch.io app. I am able to use a browser and download it, but not through the app.
**edit**
I was able to download through the app until recently. I had removed the game from one of my drives, as I was moving all itch.io games to a bigger hard drive. After I removed the game through the app, I was not able to download through the app.
