After a bit of research, this appears to be based on the French version of the show (titled "Motus"), but fortunately, there is an English option in the game, which makes it very much playable for English-speakers (and changes the title to Lingo). It was programmed by PCSL, an Irish game house, and published by Altron Corporation for the Game Boy in Europe. Carries a 1993 copyright.
I never even knew this existed, and other than the terrible background music that never stops, it's a fun game.
Also, I uploaded a gallery of screenshots
