I spent about an hour trying to bugfix why my app loaded so slowly. I was using new Store() in my preload.js file and the app hung on a blank screen for about 5 seconds before loading anything. Eventually I looked over the documentation again and realized I never called Store.initRenderer(); in my main.js file. I did that and the issue was completely fixed

The mistake is 100% on me, but I can imagine that people try out this module, make the same mistake as me, and pass on it because it seems slow. I think some sort of warning or error should be thrown if Store.initRenderer(); wasn't called.
