Hi there!
I've got a web-playable game that also has a Windows version. I had a comment that said that the version they download in the Itch app does not work. I tested it for myself and have the same issue. When downloading from the app, it appears the only option is to download the file I have marked as "This file will be played in the browser" on the project page.
I do not know why the game can't run locally after being downloaded - I spent some time trying to figure it out a while ago, but didn't have time to figure it out, so I made a Windows version as a workaround.
Is there a way to change the default download based on the user's operating system, or give them the option to download other versions?
The game in question is https://silverdubloons.itch.io/scrongly
Thanks for your time!
