The game was pretty good and all, but the thing that puzzled me is this: Jerry's father was taken when the memory version of the Marquis stepped into Jerry's world, but what of Jerry's dog. Why did the dog vanish along with Mr. Hazelnut as well?
Maybe his dad was the one who gave him the dog and therefore without Mr. Hazelnut, there was no one to give Jerry the dog.
Other than meta reasons like “it's for kids” and whatnot, why did the lizards never do anything to Jerry? They threaten him, but never do anything even when they realize that he's not affected by their spell.
