The game is about finding out what the individual can sense, and developing patterns for similarities. Our daughterfu can not tell certain colours apart, but can smell and group them up as such by that quality. It also denotes value systems as far as what one desires, such as the Kraken liking shiny objects, possibly other's playing the game are trying to develop patterns for those things. That's my guess.

"All the North African guys I know speak English and 2 or more other languages, yet they have numerous species which have different ways of functioning which would make it harder. " It's because they have different species that it's harder to establish a unified language. The closest thing they have to a language that almost any monster can use is Harpy or Lamia probably. The lamias and harpies don't appear able to be able to hear inter-species so spoken language is out. Species without the ability to smell means werewolf and werecat are out. Until we meet a ghost, the only languages left are pure sign languages since the only unifying characteristics between monsters is they have a physical form.
It also doesn't help that there's obviously a complete lack of authority in the place. Culture and language will only remain stable if someone has enough power to establish rules and permanence for culture and practice to develop. You'll see this crop up on an intra-species basis, but given the physical limitations of each species, pidgin is all you're going to get until some Demon King goes full Shi Huang Di promotes a unified language for the area, and kills anyone who promotes other languages.
