Here's a tip for all of you complaining about lag: type in "/frame" at the end of the URL (and then press enter). This will bring you to a screen with just the game and no chat.
Nazo: it IS possible, and I know because I've done it. Keep practicing and maybe try playing the game in frame mode(type in /frame at the end of the URL). That'll prevent lag. Keep trying; anyone is capable of acheiving it with some practice.
