Alright
I still think this is somewhat lacking though, I don't know I mean you have plenty of information and it's good to see you are talking about whistling submissions and how to. Still not too keen on all the text though and the red font doesn't work too well with the orange background. The audio is fine, which is great to have and all, as well as a mute button.
You added a quiz to this which is good but one major problem with this is that the questions aren't based on the information in the flash. I would suggest basing questions on the content of the flash, but it's good the way it seems to have been done with a try again method. Although still somewhat simple, a scoring system and such would be decent.
Not sure what more you could really add to this, a more entertaining way to present the main information would be a decent idea. I mean the quiz is a simple way to get information across but surly you can think of some clever way to get the main talking parts across. Try some wacky animation some time with some way of bringing points in.
3/5
