Not awful, but still not perfect
Ok, first off a bug I found, the Amusement Ride and Ante Up music descriptions appear when you scroll the mouse over the area they are located in instead of just the buttons
In terms of style, it tends to be a bit heavy and insulting. You're aiding people, so calling them 'noobs' and swearing a lot might not help that much.
The second page could be a bit clearer (by "a * sort of thing" I assume you mean the centre-point of the movieclip), in which case you could point out that this is the 'clicking point' of the mouse or whatever.
Overall its as lot better than some tutorials I've seen, but you don't cover a lot of ground. If the text for your tutorial can fit into essentially two pages, why not stretch it out with step-by-step screenshots and things?
The best thing about tutorial is the look. It's very easy to read and looks nice too. It seems reasonably friendly and accessible, which is what you want from a tutorial.
One other thing I'll mention is the music issue. Its a problem whenever people submit tutorials with music - the ballance between variety, length and loading times is a hard one. In this case I'd say a four page tutorial is not worth 6 MB and the loading time that comes with it. I'd just pick one song.
I hope this isn't all too negative, I'm just trying to give you a fair amount of feedback and as many pointers for areas to improve in as possible.
