It is possible to run away from him! The game is quite short, so I tried to make it quite tricky in some areas! If you are talking about the first chase sequence. Before the cut scene starts have your hands on the button you used to walk left with and the shift key or the running button, and then press it as soon as the cut scene is over. You gotta time it quick. After that you gotta hide. Their is a hiding spot in one of the rooms, Before the chase scene starts you can actually find it and Amy will say "This looks like a good place to hide" Thank you once again, I hope you enjoy it!
