Reception
GamePro writer 'Riff Raff' gave Bugs Bunny Crazy Castle 2 a fairly positive review, opining that "with smooth animation, good fun, and lively action, Bugs Bunny on the Game Boy is actually better than the NES version."[1] In August 1998, the Hugo version received a "Platinum" sales award from the Verband der Unterhaltungssoftware Deutschland (VUD), indicating sales of at least 200,000 units across Germany, Austria and Switzerland.[2]
