Aesthetically, you don’t need to look far to see that this game (and the original cartoon) is a Disney interpretation of Batman. With his grappling hook moves, sharp wit, and brooding tone, Darkwing could comfortably hold the title of Caped Crusader. And no one would be able to deny that he couldn't hold his own in today’s superhero brawlers like Marvel vs Capcom.
As a platformer, this game was notoriously hard. You only have two hit points, the controls can be a little fiddly, and your jumping and grappling have to be pixel perfect. The difficulty curve is most likely because of its producer, Tokuro Fujiwara, who also created Capcom classics like Ghosts and Goblins.
Fujiwara went on to create his own studio, Whoopee Camp, which made the Tomba platformers for PlayStation. These were very well received, and helped to cement Fujiwara’s reputation as a developer of very hard games!
