Warblade..Galaga Clone anyone playing?

I am a long time fan of the Atari Console and commercial classic "Galaga".
I wore it out on my Coleco Vision. Warblade is a clone and vey impressive. My wife and I are becoming addicted. i am interested to know if anyone else has played this because I have a question. Somehow, while navigating the minefield, I was awarded 10 mil points and I am at a loss as to how i accomplished this. I know i triggered a bonus somehow, but can't figure it out. The online FAQ doesn't help. Anybody out there have a clue??
A Google search will find the download site and the free version is worth the download, and after your hooked, it's worth the $15 bucks. I guarantee that if you liked Galaga, you will love this.
