Im having trouble on chapter 3 level 3, Any help would be great! This is the first time i have been stuck, and now ive been stuck for 2hours. Im at the part where the building is ready to explode and you go upstairs to where the docter is in the cell. You let him out and he is suppose to take you down the elevator. In my game he walks over to the elevator and does nothing. This is where i have been stuck!!!
