Js responsive

Hello, my website is HTML5 responsive. I would like to built a js game that is also responsive.

My problem is that when I joined the script, the game appears very small(look screeshoot). when I change the values gamewidth values ': ‘100%’, ‘gameheight’: ‘100% in gamewidth’: ‘600px’, ‘gameheight’: ‘600px’, the games is not responsive … how to correct the problem?

<script type='text/javascript' id=198972>
(function(d, gn,scriptId){
var prop = {'agent': 'publisher', 'bgcolor':'#fff', 'wrapperwidth':'100%', 'wrapperheight':'100%', 'gamewidth':'100%', 'gameheight':'100%', 'fullscreen_on_mobile':'true'};    jsid = 'sgEmbedJS';if( d.getElementById(jsid) ) {embed(d,scriptId,gn, prop); } else {
var s = d.createElement('script'); s.id = jsid; s.type = 'text/javascript'; s.onload = function(){embed(d,scriptId,gn, prop);};
s.src='http://publishers.softgames.de/embedder.js'; d.getElementsByTagName('head')[0].appendChild(s);}
