Today I noticed an update for the game... what has been updated?

I have just tried to run it, clicked some menus and it seems like it is working fine on Windows 10.

It already worked well on Windows 10...

Think it may be that the game is back at GOG,

i was weird seing the news post about the lauch of this game,
when i was pretty sure is was here alredy, or something similar.
Then i found out that it had been remove from store late last year.

soo, the update may just have been a change of publisher on librarys.

They transcoded the videofiles from Indeo 4.1 to MJPG and added some DirectX wrapper and DirectX 9 to the installer.
Look at the screenshots for further details. I picked the Intro video as example.
