Hi Tia347, could you give me any more information about the problem you're having? I've tested all the downloads again on Windows 10 and I'm not seeing any problems.
Does the link on Itch.io not download anything? Or does the zip file not open after downloading? Or are there any errors when opening GB Studio after downloading? If there are any errors could you list them? Are you downloading using the Itch.io website or the Itch.io app? Any information you can give me about exactly what's happening will be a great help and I'll try to get this sorted :-)
