I know you haven't asked for people's opinions but hopefully this can help you out! You've done a good job overall with the template but it's not really suited to a game. Also using standard gradients doesn't seem to be very popular anymore, I'd try using more textures or sticking with flat design. I'd use some form of boxes/dividers on the menu to make it easier to click and navigate through the site. Sticking to a completely grey palette can also make the site look very dull.
