Frank's Adventure Simply the best!
I once stumbled over this series, and was immediately stunned.
At the time I played part one, we learned how to use FLASH at school, so I was very interested in how these games would work.
So they became something like my all-time-favourites (even my fiancee loves them ;) )
As for all the other Parts: Niiiiice work all the way! Two Thumbs Up!
