I stumbled upon a YouTube video of a game rip for the soundtrack to the CD-i version of the game Dimo's Quest. The music is fantastic, so I wanted to know who composed it. I found a full playthrough video of the game and Joris de Man is credited for all music.

Note that the DOS version of Dimo's Quest has a completely different soundtrack by Thomas Detert.
