Gamecljsprotocol
A game object contains the internal renderer object and various bits of state
that are important to the overall execution of the game. Every play-cljs game
should create just one such object by calling create-game.

Screencljsprotocol
A screen object provides the basic lifecycle for a game. Simple games may only need to have one screen. They are a useful way to isolate different aspects of your game. For example, you could make one screen display the title and menu, and another screen contain the game itself.
You can create a screen by using reify like this:
(def main-screen
(reify p/Screen
(on-show [this])
(on-hide [this])
(on-render [this])))
