About Daiku No Gen San: Hammerin' Harry
I first played Hammerin' Harry on the NES back in 1991, a game developed and published by Irem. It was a solid platformer from that era, a time when side scrolling action games were a staple of the console, and it held its own among the many titles vying for attention.
You control Harry, a carpenter who fights through city streets and construction sites using his hammer. Your main goal is to rescue your girlfriend from a gang of thugs, moving screen by screen through levels filled with enemies. The core mechanics are straightforward: you swing your hammer to defeat foes, and you can also pick up and throw certain items you find. The pacing is fast, and the difficulty ramps up quickly, demanding precise jumps and timely attacks to progress. It feels satisfying to land a solid hit and clear a path forward through the urban chaos.
