Principle: Exaggerated Proportion
Describing FORM: What is the specific communicative strategy? Where is it found?
Proportion is the size relationship of different part(s) to the whole. Exaggerated proportion is when one particular object is larger/out of scale. The characters in this game are crossovers from other games, but in this game - their proportions particularly their heads are bigger than their bodies.
Describing Content? What does it communicate?
Japanese games adopted the "chibi" characters where they are short, but maintain their head size. In a sense, the characters give off a cute, heartwarming, and less serious type of feeling.
