Would like some comments on my first stab at Ember

GitHub - jschaftenaar/ember-easter-egg: Ember Easter Egg Demo is my first stab at something Ember, it is a small component that creates an old style game of snake. I know it is not fully Ember yet but would like to get some suggestions on how to improve this. I already know there can be some performance improvements and I want to pour it into an addon format. All suggestions are appreciated.
