As far as I know there was never been a connection between the two, never had anything to do with the person or team that did DK on C64. Moreover I think that version was a Ghost'n'Goblins clone, as opposed to the Amiga version which I think it wasn't.
MaxAg. Shadow of the Beast for sure. I remember that the parallax layers for the graphics and the Pan's flute for the music completely excited us.
Yes, I'm lead programmer at ForwardGames on Notcom Racing. Nicola also is taking care of the whole audio side of the project, so I have the pleasure to work with him once again.
I really am a C64 fan, but on the Amiga Shadow of the Beast, definitely.
