Play Daiku No Gen San: Hammerin' Harry Online
Swing a comically oversized hammer through chaotic construction sites, smashing goons and dodging wrecking balls to a ridiculously catchy soundtrack. Pure NES catharsis in overalls.

Game Overview
Hammerin' Harry (or Daiku no Gen-san if you're feeling fancy) is one of those NES platformers that somehow makes smashing things with a hammer feel weirdly satisfying. You play as a construction worker taking on corrupt businessmen and thugs—basically, the plot is "angry blue-collar guy fights back," which honestly still holds up.
The controls are simple—jump, hammer, repeat—but the levels throw some clever twists at you. One minute you're knocking out goons on scaffolding, the next you're dodging wrecking balls or hopping across floating platforms. The music’s got that classic Irem energy too—upbeat, slightly chaotic, and impossible to get out of your head after playing.
It’s not the deepest game, but there’s something charming about how committed it is to the bit. You’ll probably finish it in an afternoon, but you’ll have fun doing it.
