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 the ability to jump; 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.
Plot

Development
The North American NES game is a modified version of the Japan-exclusive Family Computer Disk System title, Roger Rabbit. Roger Rabbit is the game's playable character, all the villains are Who Framed Roger Rabbit-related, and hearts are collected. Due to Capcom owning the rights to develop and publish Disney film-based video games, as well as LJN already having published Rare's own video game adaptation of the film, Kemco decided to use Bugs Bunny, due to he and Roger both being rabbits, making it easier for Kemco to modify the Roger Rabbit game and release it outside Japan as The Bugs Bunny Crazy Castle. For the Game Boy version, Kemco's license to develop and/or publish video games based on Who Framed Roger Rabbit became outdated; however, they still had the license to create Disney-based video games, which they used to create Mickey Mouse for Game Boy. An early beta version of the game shows the working title as Bugs Bunny Fun House. In 1997, Kemco released the Game Boy version along with The Bugs Bunny Crazy Castle 2 in one cartridge under the name Bugs Bunny Collection GB.
Reception
The Bugs Bunny Crazy Castle had mostly positive reception. The Game Boy version was the most popular and received critical praise. The NES version was also a commercial success.
