Some guy named Fritz goes to a series of ramshackle old mansions to, I guess exorcise them by destroying all the crystal balls therein. Each house is also infested with various kinds of monsters: ghosts, frankenstein's monsters, witches, and so on. Each house is divided into four screens, and each screen has four floors on it, with stairs and doorways being the way to get between floors. Most of the time, the player can only see the floor they are on, though there is an item that appears in each stage that illuminates every floor. After each orb in a house is smashed, the house starts to collapse from the top down, and the player has to rush to the exit. Failing to get to the exit before the house completely collapses results in death, obviously, but it also gives the player a different death screen than the usual, which is a nice touch.
