The game itself is a classic and as good as ever, however I bought this GOG version thinking that it has been made to work smoothly on modern computers, which sadly turned out to not be the case. This GOG version has serious bugs with the mouse control. Already in the UI the mouse sometimes jumps suddenly, but more severe is that every once in a while during the mission the mouse gets "snapped" to one of the screen sides and becomes unusable. You have to alt-tab out and kill the app. This is infuriating because you can't save during the mission, so you will lose the progress. This bug has been reported to GOG already 10 years ago but has never been fixed.
