So Jenny, do you think there may be a problem with the above mentioned games in Windows 10?
As I said, I think you may have to click past dire warnings about the game being "unsafe" because it contains Flash. I certainly had that problem with QuickTime even in Windows 8 -- and that was years ago, back when Windows versions of QuickTime had only "just" been declared unsafe.
So don't be surprised if Windows 10 does something similar when Flash is no longer officially supported.
I doubt Windows 10 will prevent you from installing and playing a Flash game any more than Windows 8 prevented me from installing QuickTime with a game, but don't be surprised if it coughs up a few warnings first.
Ideally Amanita would come up with Flash-free versions if they continue selling their older games.
