Mendel Palace (known in Japan as Quinty) is a game set in a fantasy world where a player has to fight animated dolls in search of his younger sister, a witch who took his girlfriend away (in the American version, it's a princess, but the concept's still the same). To achieve this, you have to travel through eight different dollhouses (comprised of ten rooms each, the last room being a boss battle) and attack the enemy dolls by flipping the panels from underneath them to send them flying into the wall. Once you've done that, you get to enter the witch's palace and fight her on her own turf to win back your sweetie.
