It's called Wolfietale and It's NOT where all the characters are wolves actually. It's about the underswap characters are all part-wolf and are in a "Pack" and the game would follow the journey of a human travelling through he underground in order to reach the throne room of their alpha to become one of them and not die like all the other humans who just kinda existed down there. (they kill anyone down there that's not one of them.)
Here's a trackpad drawing of it. (This took forever XD)
