It's quite easy to try all the 720 possible answers when you're playing the X360 or PS3 version. It takes about 15 minutes.

In the PC version there's another glitch. The one that keeps you from choosing an determinate time in the clock. The clicks in the mouse are not obeyed. There's no keyboard option to the clicks.

I was having such a great time playing this game and now I just CAN'T play it anymore because of this stupid flaw in the programming.

C'MON GUYS WE'RE IN 2009. These glitches are sooooo 90's
