The 90 MB .exe file converts to more than 500 MB for an HTML zip file? I haven’t done that conversion before because I don’t have access to Windows to check the game play.
That’s a huge difference that doesn’t make sense to me, with how small HTML, CSS, and JavaScript files typically are.
But, okay. I guess you’ll just have to wait to find out who trusts an unknown developer with a format often used for malware.
