Really good

This is the reason The net was made.

Can't see any bad points. well done!

lol

It was funny,
but next time try to put the frame rate at 24 or 30.

so bad

this was really bad animating...
but is was funny as hell!

Good

Just Improve the graphics, make it a bit faster (maybe make the persons smaller so the action can be a bit faster while you still have the same time to react).

And be a bit more original, but that is hardly a point to blam a flash.

All in all a nice (although mediocre) defense game.

Really good

It was really good,

But I think this still is a bit "too simple", Don't get me wrong!
I know It's a hell of a job filming all the stuff.

But I mean the work in Flash itself can't be to much work.

Although the simplistic way of your weapons might actually be a good thing (don't care about reloading, just click the enemy kind of thing).

All said and done I still like it.

Rock 'n Roll racing?

This really reminds me of Rock 'n Roll racing on the snes.
I really miss those songs...
