Black space on top and left of game

Hi,

I just published my game at newgrounds.com and I notice that it shows a black space on the top and on the left of the game.

I don't think has nothing to do with newgrounds but how Construct 2 exported the game to HTML5.

Has anyone have notice this?

Here is the URL » http://www.newgrounds.com/portal/view/641154

Thanks,

Looks centred to me in IE, Firefox & Chrome.

Here is what I am talking about
