I see there's been a new update! I've tried uninstalling, reinstalling, even deleting the entire the-marked folder in itch folder so that it reinstalls it completely, and it doesn't work when I launch it in itch.io desktop app. It *does* work when I launch it in my browser independent of the desktop app, so I think it's the app specifically. Usually files with that download button have a windows or mac icon, and if they're not labeled so they have that, itch.io desktop app may not know how to run it properly, so I think that may be it?
