Forgot to mention about the Mage Dog
This is the thing that is not noticeable from the first glance, but this dog appears in the third scene in the mage world and he's making some kind of magical substance that he packs in some kind of the capsules? There are seen throughout the game and on the right from the dog when we see him for the first time. Then during the final scene in the magic world when we see a black hole we can see the same place where the dog was in the third scene. Everything there seems to be fine except the thing that the dog disappeared. Then we encounter that dog during the final scene when he sees us and disappears. The thing was that that dog helped us to return to MC home, he opened these two black holes in the magic world and the skeleton world.
Nice huh?
