tried downloading but no file showed up? i'm using the itch desktop app
Whenever this or most other download errors happen you can paste the link from the navbar in Itch to your browser and download it from there.
You don't get notified of updates, nor can you launch it from the Itch App, but you should be able to download the games.
and why won't they fix it? i have several games with that problem
and i get the app to play games with it and not without it it just makes no sense
Because it's not Itch, it's the developers of the game not ensuring it works with Itch.
I offered a workaround. If you want it to be fixed then message the developers.
