|Playable Character (Girl in White Dress)||~10||~3’3|
By doing a visual observation using this Youtube Gameplay Trailer uploaded by Gamera Games, we can that the girl is very young, probably around 10 years old.
When the girl is scaled next to a door (see at frame 0:59 in this Youtube Gameplay), she seems to be around half the height of the door. Assuming that the door in-game follows the same standard commercial door height stated on Rustica, it would give the girl a height of around 40 inches or 101cm. This estimate was further visualized using Hikaku Sitatter Height Comparison Chart.
