thank you so much, I'm glad you like it so far^^
also great suggestions! Interacting with the roaming slaves and also an expansion for the sandbox is actually planned. Not sure if it'll be in the next version but certainly at some point.
For males I'm not sure. Personally nothing against it. Might have to try that out.
For furries, I unfortunately lack the experience of creating the needed models. But maybe something I'll look into in future.
