Lots or graphical issues, slow cursor leaving trails and graphical errors. No custom resolution options unless you run an unsupported tool that has options in German and usually results in the game failing to start and not being able to exit from a black screen. Tried on 2 Windows 8 machines with the same issues.
The game is great, a little difficult at times to know if you are making progress, but that is the 'old school' nature of these games. The major issue I am having, and the subsequent removal of stars, is the relatively often game lock-ups forcing me to log off and on again as the game window becomes unresponsive and the menu stops working, preventing task manager to get to the front. Not often enough to for me to give up on it, but usually prematurely ends a session. I'm running Windows 8.
