Hammerin' Harry, also known as Daiku no Gen-san (大工の源さん, Carpenter Gen), is a platforming game that was developed by Irem for the arcades. It was later ported over to the NES with some features removed and was released only in Japan and Europe. You play as Harry (or Genzo Tamura" in the Japanese version), a carpenter by trade who finds himself harassed by a rival carpenter company, who destroys his house and kidnaps his friends. He's now out to take revenge with nothing but a huge mallet and smash the rival company's business down until there's nothing left while also rescuing his friends.
Bloopiero improves on their previous movie by almost 3 seconds thanks to some enemy manipulation, lag reduction, and other strategies.
