Code wise it is not too difficult. The main issue is the artwork. About half the animals, like rats and mongrel, have a directional facing so it will work well for them. The other half, like spiders and golems, don't, so they will have no effect and will require changes. Plus the current player image, a place holder for now, isn't directional either.
Hopefully dynamic player images will come soon, maybe within a month, so I would need to decide before I draw the base images, whether to do this or not. Will draw some test images before I decide.
But cosmetic things like this will be important if we want to attract and keep a more diverse player base.
