traditional arcade concept with no real surprises. the major real estate of your site is allocated for adsense, which, if you don't turn enough money through adsense, i'd rather use the that space for my own branding.
Player rankings and most popular should be higher up on the left skyscraper as these are the elements that can drive your user participation.
Somehow, and that may only be me, it seems that site is a bit out of focus, somewhat grainy, distorted - not sharp.
Other than that, it's still a non surprising arcade script, "the usual", which doesn't get to say that your site is bad, just not outstanding. :imho:
