Yes, I finally got it to work. You have to go to your web page not on the itch desktop app, download, then run the .exe file. Somehow I missed a step earlier. Great game!
However, just a general comment I want to make. I am not putting any blame on you, I think this is an itch problem, but their UI and explanation about issues like this is minimal or non-existent. I know they are a small team but the latest publicity they have received due to bundles and whatnot should hopefully get them some funds to work on this platform. I will continue to use it of course, I really like playing and testing indie games, but if you any influence on them please tell them - FIX and IMPROVE your platform PLEASE!
