Layer and Rendering Question

Thanks.
Right now i tested just basic background map render, moving with player, collision, and its working fine, i didnt notice any performance drop or any lag. I think i dont even need layering system, but i will follow and test more. Im using nwjs chromium because its going to be pc game, not a mobile or browser and its working perfectly.

I was using my custom code and it was also working good even without layers so i think that phaser will do even more!
