My hopes have been dashed with the message "not available on Windows"! (A friend sent the link to me, I don't know what platform it is originally intended for.) Looks like a super fun game--I love seeing creative variations on pinball mechanics!
Where are you getting this message? The game should be playable on Windows, as it was made in Game Maker Studio 2. However, it isn’t currently playable on Mac, because a Mac OS computer is unfortunately required to export for the platform even if you own a license to do so. (I’ve considered borrowing or purchasing a laptop to export later builds, so Mac users don’t despair.)
I have been using the itch.io app on desktop (in Windows 10). I prefer the desktop app over the browser site since installing games from the app keeps it all nice and tidy in a hidden folder instead of cluttering the downloads/desktop.
I wonder if it's an issue with certain file types--shortly after I made the original comment ,I was looking at a friend's game that also showed this message in the app, even though it was definitely a Windows-compatible executable. Now that I am looking at your game on the web browser, it lets me download it just fine.
