They actually have. If I'm not mistaken it was actually Brolaren. Try to search their patreon, there is a bunch if people, who worked with shitpurple(and cool artists too!), but left for SOME MYSTERIOUS REASON. Team changed several times.

I know, I was there during one of the earlier outbreaks when former BreedingSeason team members provided some interesting stories with sccreens. I was there Gandalf, it was 3000 years ago. Now I just reminding that story from time to time so new summer children don't get into that shit trap.
I mean the monster on monster cg not the monster with the Player, I know he made all the player and monster animations and the characters for the game, what I mean by monster on monster cg is full on animation like monsters with players but instead with other monsters like wolves with holstar, cats with wolves and dragons with centaurs etc
