Unity5 WebGL Build Analysis

One more LIKE to unity for this Webgl port. Once if any animation, video and even images are flash in a website. As internet developed more new and better tools evolved like ajax, css3, html5, js, jquery... and as a game developer i see webgl as major development.
Plugin free game running in browser. This is one of the major feature which will game to reach a lot of people.
I had tried earlier webgl when introduced in a Linux environment with chromiu, then with three.js, now with unity 5.

Now I planned to port my Android game ZnopChains to webgl and publish the game online.
Upgraded the unity4 project to unity5, removed plugins like Unity Ads, Google play Achiments and Highscore, Soomla from the code. And fixed all errors because of this code removals.
