Hey there, not sure if the Itch App can't open Zip files. If all else fails a manual download, unzip the game and just click the executable.
I looked around a bit and tested on one of my own projects. I think it's because you didn't tick the checkboxes for what OS it's for. On your file it doesn't have the Windows logo next to it like other files I've seen have.
Worth a shot maybe? :D
Oh, Thank you. I absolutely skimmed over that. Fixed now. :)
