There's a lot of work in that website! I applaud all those who have taken the time to put it together. Really good effort.
Now, criticisms (you knew it was coming!).
The sound effects I find really annoying. Not really necessary in my opinion. I would ditch them.
The entire site needs a good proofread (spelling, grammar and consistency) because there are rather a lot of errors in this regard. While this may not be noticeable to some people it does rather detract from the very professional look.
The scrolling writing in the red 'net' top border thing is really hard to read, both due to speed and colour contrast.
When proofing the site make sure stuff is aligned properly. It can be a minor but constant irritation to keep on seeing edges and stuff not quite lining up.
That's all for now. I may have a really in depth read of the site when I get the time, but the thoughts above were what leaped out on an initial scan.
Sorry, not trying to be negative. Overall the site is really fantastic!
