Sorry for the delay. Weird. I logged back onto Itch tonight and it looks like it had downloaded. What it was doing is that when you click on Download (I'm using the Windows app) it takes you to a screen where there is a dropdown that is either populated with the filename or to select a file if there are more than one. That dropdown was blank with no file and kept giving me an error message when I tried to click Install. I've had this happen a few other times with other games on Itch as well. Either way, it's working. I'm glad I was able to play your game, it is quite good. :-)
