Krusty's Fun House, released as Krusty World(クリスティーワールド,Kurisutī Wārudo?) in Japan, is a video game based on the cartoon seriesThe Simpsons. Originally named Rat-Trap, it was developed by Fox Williams for the British software house Audiogenic, who licensed it to Acclaim Entertainment, the U.S.-based publishers of a range of games based on The Simpsons.
The player directs small rats to an extermination area through complicated maze-like levels. The player controls Krusty the Clown, who must navigate through his Krusty Brand Fun House. Each level is a puzzle in which a number of rats must be exterminated. Using different objects and obstacles, Krusty must create a path for the rats to follow and guide them towards an extermination device. Other creatures such as snakes and flying pigs attempt to hinder Krusty's progress by injuring him; he must throw pies in order to defeat them.
Super Play magazine gave the SNES version of the game a 79 percent rating and wrote "it's actually pretty good fun to play, although perhaps more of a Younger Player-oriented game than anything else. Not one to set your heart on fire, but a good solid game nevertheless."
