I'm glad you're enjoying the game :)) I've put a lot of heart and soul into it!
As of now, Brookes does get taller after eating Karia'rashi! But other than that, there would have to many too many alts of her different forms to add something like the bigger tusks or stuff visually. There is however lots of different dialogue for her where she talks more monsterous on the vore route! She's def supposed to be portrayed as chaotic evil on this track! (I just need to figure out how to update her biography on the Status page!)
Other than that, we'll have the slime filled status affect pretty soon. And maybe a petrified one as well. But that's about it for this game!
