It is a homage to the Capcom classic: a revisitation that refuses modernization, mixes elements from the two original episodes and ties it all together using difficulty as the glue. It is in fact a real challenge that the game offers, made up of countless unsuccessful attempts and inevitable episodes of burning frustration, but at the same time capable of returning great satisfaction the moment one manages to overcome a very hostile point in the campaign or defeat a seemingly invincible boss. Just like in those old arcades of the late 1980s.
