Oh wow, that was really cute. I love how the kid just telepathically lifts all objects up and takes them to construct it's castle. I just took almost every item and placed it in there!
I find it really creative how the rules and puzzles are direct translations of what limits and obstacles a real kid doing this would face (feeding the cat to get a chocolate, not being allowed to take the parent's blanket, having to stay in a bound, etc.).
