Top banner: just one one exclamation mark User panel: make it so the text fields become clear when you click on them to type username/password, like the search bar at the top. I don't see the pictures for the games, that's really bad. Your visitors need to see a preview/screenshot for every flash game you have or they will never click there and play. Even when I do click on it, it says the game is loaded but nothing happens, so fix that bug.
Yup I agree. Change the logo. and like outspan mention go easy on the exclamation mark. I like sites with colours and would recommend you adding some to the background. Cheers
