Haven't heard anything about that either and also agree that this is indeed a very fun one. Something that could be tried maybe:
The game could maybe be described as basically "reverse balderdash" because instead of definitions for not well known words you make nonexisting words for certain definitions, so maybe this could be played using the answersides from balderdash cards. In addition you could use some scrabble tiles (just have to sort them by consonants and vowels) or just write up some letters von paper.
Just a suggestion as this is really a fun one, would be great if someone made an english version, I think the game deseveres some spotlight.
