The Bugs Bunny Crazy Castle

The Bugs Bunny Crazy Castle, known in Japan as Roger Rabbit for the Family Computer Disk System is a 1989 action-puzzle video game developed by Kemco for the Nintendo Entertainment System. It was also released for the Game Boy in Japan as Mickey Mouse and in North America as the same name as the North American NES release. It is the first game in Kemco's Crazy Castle series and the only one that was released for a home console; each of the four subsequent games in the series were released on handheld devices. (This only includes games with the Crazy Castle title; a game in the Japanese Mickey Mouse series was reworked into Kid Klown in Night Mayor World, which saw an NES release and a sequel on Super NES but was not otherwise connected with the North American Crazy Castle games.)

Three different versions starred three different cartoon characters: Bugs Bunny, and Disney's Roger Rabbit and Mickey Mouse, and were first released in 1989. The object of the game is to guide Bugs through a series of rooms collecting carrots. However, four rascals are guarding the castle: Sylvester, Daffy Duck, Yosemite Sam, and Wile E. Coyote.

While presented in a side-scroller format, Crazy Castle differed from standard side-scrollers such as Super Mario Bros. in that Bugs Bunny did not have a jump function; therefore, only by taking different routes could Bugs avoid enemies. Some of the levels had boxing gloves, invincibility potions, safes, crates, flower pots, or ten-pound weights that could be used against the enemies in the game. As a result, the game had a 'puzzle-solving' atmosphere.

Players score 100 points for every carrot with the last one in each floor giving the player an extra life, 100 points for every enemy defeated using invincibility bottles, 500 points per enemy using boxing glove and 1000 points per enemy that gets hit with heavy objects. Because most NES game cartridges lacked the ability to save, passwords can be used to start at a certain level in this game.
