--- Comment #8 from A Wine user RandomAccountName@mail.com 2010-03-10 09:45:50 --- I finally found a demo for this game which shows the same behavior; adding that to the URL field.
Note that the game itself has a bug where it will crash immediately if too much processing power is available, so you might need to have a CPU-intensive program running in the background or something to get it to start.
