The Bugs Bunny Crazy Castle: 1990
Developer: Kotobuki System
Genre: Puzzle

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.
