Vengeful Bat Dungeon Crawler

A short adventure RPG where you play as a bat, a rat, and a wolf, and descend into a multi-level dungeon in order to get revenge on the humans that murdered your family! Instead of playing as heroes in a typical RPG you assume the role of the monsters they fought along the way.

A bat's family is slain, and it is the lone survivor. An innkeeper that loves animals puts the bat in a basket to rest. The bat then tracks down the adventurers and seeks his vengeance.
