Revealing mistake: In the Kitchen of Barber's Mansion, when you put the canteen under the water spout to fill it with water, you can see the sprite of the canteen is just put over the top of the water animation, as the water is visible underneath it.
Continuity mistake: In the opening cutscene, when the mechanical bird, Mathew, shows a projection video display, it is in full color. But any other time during actual game play and cut scenes, the projection from Mathew is a grainy black and white.
