Play Ganbare! Daiku No Gen-san (japan) Online

Ganbare! Daiku No Gen-san came out for the Super Nintendo in 1993, developed by Irem. It was part of that wave of Japanese platformers that didn't always make it overseas, so you had to seek it out. The game puts you in the overalls of Gen, a carpenter who has to rescue his kidnapped girlfriend from a gang of thugs.

You control Gen through side scrolling levels, using your hammer as your main tool for both combat and interacting with the environment. The main goal is straightforward: fight through each stage to reach the boss and progress. A key mechanic is the ability to build temporary platforms by hitting floating nails with your hammer, which adds a puzzle element to the navigation. You also collect power ups, like a super hammer for stronger attacks, and health restoring bento boxes. The pacing is fast, and the difficulty can be unforgiving with precise jumps and aggressive enemies. Playing it feels like a frantic, hands on scramble where you are constantly swinging your hammer to survive.
