Yeah that'd be in the plans at some point. Once the game is near completion, I can make a list of some sort that explains my process. To add new logic would be tough (the unique things that some predators have, like Succubus checking every 3-4 hours to see if her prey is active enough), but if you don't mind copy/pasting the behaviors a current predator has, then the process of adding a new predator should be easy enough to explain. I just have no idea how modular or easily sharable it would be; I don't think the game has the ability to not exist as one whole piece. The game currently does not have a way to load a character from outside of itself. If a modder were to supply everything required for a new character, anyone playing it would need to download the whole game to see it unless new logic is added for this. Not sure if I'm explaining this right, it's a bit late here.
