Ancient-Red-Dragon: I also have the problem with the game permanently running as a Window. As far as I can tell, there is no option to change it.
I don't want the game to run as a Window.
What is the solution to this?
I second this notion: I, too, prefer to play in full-screen.
One more thing: when zoomed out the game looks 'blurry' and the scrolling slows down to a crawl. Neither the original nor the fan-made widescreen patch had these problems, is there any way to fix them? They are not game-breaking but it would certainly improve the overall aesthetics. (On the other hand: finally there's a way to play the demo level in widescreen, yay!)
