A lot of the tutorials I've seen are either too specific (like one technique that can only be used in Flash MX) or are so basic that they're almost useless. Your tutorial on the other hand is has quite a lot to offer and very helpful.

However, in the Newgrounds section, I did notice a few mistakes.

It's not level 10 when it depends on how much exp HT52 has, its level 9.

The number of points actually needed for the ranks are different from the amount it says in the FAQ (you can look on the Top 50 B/P list and see for yourself that some of the FAQ numbers are wrong) and you either added or missed a number for others. The numbers that should be in your list are:
Police Sergeant 400 (you typed 4500)
EG Staff Sergeant 4,000 (You somehow missed the rank)
EG First Lieutenant 11,000 (missed a 0)
EG Major 14,000 (missed a 0)
EG Brigadier General 19,500 (you guessed it, 0)
EG Major General 21,500 (the FAQ was wrong)
EG Lieutenant General 23,500 (ditto)
EG General 25,500 (bad FAQ, bad).

Movies cannot be whistled because they are REALLY bad (unless you mean bad by unsuitable and not by "crappy movie").

I wish I could get a gold whistle with 30 reviews; the amount needed to get it is much, MUCH higher. The number of reviews to get the gold whistle depends on the amount the user with the deity (not diety) whistle. There can also be more than one deity (and there can also be more than one level 30 user) if they have the same number of points.

For the third secret you can only choose one game and you get it at 1,000 exp points, which is smaller than the amount needed for level 10.

There is no E+ for Batting Averages.

And in the Dictionary section (which could be expanded) I always thought <3 meant love, but I could be wrong.

Other than that, this is tutorial gold, well done.

There only one level with no music or sound and the time limit seemed short, with the reset button coming up with 2 seconds to go. It was too simple for me, grabbing a file, put it in a folder, repeat.
With the ranks, I thought this would be better if it had a NG theme with swf files needing to be blammed. You could add some variety and put in files that you shouldn't click on or something so the game seems more interesting.
I repeat, it's ok, but it needs more.

This game was planned well, except for that section where you couldn't fall off the edge (or you would lose life), that was annoying when I went there the fifth time.
As for Trapped 5, I recommend that you should put extra lives around, especially if it requires more thinking than this one. I hope that you get enough ideas so that Trapped 5 is the best game yet.
