ThePixelWorld requires to load some huge map files, in case u have trouble:<br>
Firefox dev tools network inspector truncates responses to 1MB by default.<br>
You can change or disable the limit by navigating to <b>about:config</b><br>
and changing <b>devtools.netmonitor.responseBodyLimit</b>.<br>
To disable the limit, set it to <b>0</b>.

<h3>News:</h3>
I have some trouble while parsing tmx maps.<br>
currently we are using just a sprite file as "map" :D<br>
<h3>ToDo</h3>
