Game is great for 30 minutes..then if you are unlucky you can't make it past 2nd level because of a timing bug. This is not my system specs, they all are in excess of min req. plus i tried turning all graphics down to lowest and made sure noone was encumbered. It is clearly some kind of bug. There are many complaints in threads on internet, I would advise anyone NOT TO BUY THIS GAME until you find something in writing from developers stating this is fixed.. Consider yourself warned
