Extending this multimethod allows you to create new entity types.
In this example, we create a new entity type called :smiley that draws a smiley face.
After defining the method, it can be rendered like this: [:smiley {:x 0 :y 0}]
(defmethod
play-cljs.core/draw-sketch!
:smiley
[game renderer content parent-opts]
(let
[[_ opts & children]
