Hammerin’ Harry

Hammerin' Harry, known in Japan as Daiku no Gen-san, is a series of platforming video games developed and published by Irem in 1990. The titles were developed and published for the arcades, Famicom, Game Boy, Super Famicom and Sony PSP platforms. The series is centered around the titular Harry (or 'Genzo Tamura' in the original Japanese), a hammer-wielding carpenter who protects his hometown of Beranme from the corrupt construction companies that mean to tear it down.

In the peaceful town of Carpentersville, some workers known as The Rusty Nailers decide to bulldoze a house that belongs to Harry. Harry is certainly not happy with this, and goes on a rampage, destroying workers that get in his way. As Harry, you can destroy workers in one of two ways: you can smash them when one of them gets near them, or you can pound the ground, and by doing this, you will send shockwaves in both directions.

There are four environments in which Harry needs to get through: construction sites, sewer, ship, and the mansion where Harry meets the leader who ordered the demolition of his house. At the end of each environment, a boss needs to be defeated in order to proceed to the next environment. In between these, there are bonus stages in which you have to destroy a number of enemies before time runs out.
