Excessively simple, and since you can take your circle from your side and put it on the other, you can overlap the opponents and easily score points.
Good engine - weird plot
The game itself is pretty good save for the controls - they were a little tricky. The plot though is very strange. [Spoiler alert!] The idea that somehow russians would pull super-weapons out of their ass and that one random dude in nothing more than a t-shirt armed with a sole handgun could stop them is absurd. In the background graphics (which were nicely made may I add) there are crates of AK-47s lying around and yet you are being shot at by some pansies with handguns. Not very realistic at all.
On the other hand the cut scene comics were nicely made. Keep it up and try to come up with a plot that's a little more realistic if that's what you're going for.
This is one of the worst tutorials of flash that i've ever seen. How about you look at what other people have done and try to make yours BETTER than that; not worse. Here's an example of a good starting-off-in-flash tutorial:
