Beautiful game but resource hungry

I installed this game on my new 2013 Macbook Pro Retina. The graphics and concept of the game is very good. However after a few minutes the fan would start spinning really loudly and the battery drains very quickly when running this game. I am not running any other application while playing this game so this seems odd that a simple game like this could be so resource hungry. I hope an update comes out that would fix this.
