WELL.
It's been a while, has it not?
I've had a look at the Feral Tales, and while this game probably won't draw me in as much as FeralHeart, it looks very nice - if only in early stages. Facebook games aren't really my thing.
If Kovu intends to give out the code, he shall do so.
I, personally, think it would be a nice thought to give the MODs of FeralHeart an early viewing of said code, or to give it to them full stop to do with it what they will. This game hasn't had any updates in yonks, and it would surely attract more members and bring back old hands if there were new things to derp about with.
If the code becomes open-source, well. There will be a lot of similar games around no?
