My biggest problem with it is the characters faces and like you said Pixies size. The drastic change in setting for the world is also seriously going to effect the story. Like how people act and how the character would make an impact later. If certain mechanics or the powers are gone or not the same, then this really isn't the same story, since they were so relevant to the original plot. Since some relationships don't happen without the control or break powers. Later on they had relevant use outside relationships such as interrogation and dealing with enemies.
Based on this version CK v0.2.1, the world and therefore the story is way too different from the original. We originally arrived by train at the city station inside the city with the concept of Fey or other creatures being fantasy and not real, and met up with Jessica then got a room or apartment and meet Emma that way as our neighbor. Not something grand like a resort where Jess is the owner and Emma is cleaner. Way too much has changed right from the get go.
