I really liked the concept of exploring grandpa's house full of magic and riddles. The objects in the house, the gadgets, and the magic book of a sidekick perfectly illustrated the concept, and I really enjoyed exploring the house!
I especially like the conversation between Book Queen and Mr. Shapeshiefter. I love that she is the mother of the book! I also love the fact that Mr.Shapeshifter is exploring with us to keep his promise to his grandfather!
What I noticed was the camera movement. I got a little bit of 3D sickness, probably because the camera instantly moves in the direction of movement when I move.
