During the scene in Rick's house when Scissorman is watching cartoons, the flowers in the pot disappear and then reappear later on.
During the scene at the end of the game, when Helen is hanging onto the bar, Gotts is seen trying to make is way toward her. He appears to be holding onto the wall for support, but if you look at his shadow, he is nowhere near the wall. When the camera switches to Helen, and then back to Gotts, he has magically transported right next to the wall.
