Glad you like it! I was planning to add dragons and I do like the idea of having hellhounds too, although I'm not sure when I'll get to add either. Same goes for knotting.
As for images, there probably won't be any for a long time
I do have some more fun little suggestions if you desire!
In terms of general monster additions, perhaps we could see some harpies too! Or perhaps taurs. There's also raccoons and squirrels, which could drop an item like some food when the encounter ends!
Im definitely adding squirrels when i can. As the dropping stuff, I was planning on making some monsters drop food or other items (depending on the species) after an encounter if your relation with them is high enough.
