Play Sakigake!! Otoko Juku - Meioutou Kessen (japan) Online

I picked up Sakigake!! Otoko Juku: Meioutou Kessen for the Game Boy around 1990. It was published by Bandai, one of the many manga and anime licenses they adapted for Nintendo's handheld. This was during the early years of the Game Boy, when developers were still figuring out how to translate complex action into that small, monochrome screen.

You control Momotaro Tsurugi, the main character from the series, as you fight through side-scrolling stages. Your main goal is to defeat rival students from other schools using punches, kicks, and special moves. The game uses a screen by screen progression; you clear all the enemies on one screen before you can move to the next. You can also collect power-ups to strengthen your attacks, and the pacing is quite fast, with enemies swarming you constantly. It feels like a straightforward brawler that captures the simple, aggressive spirit of the source material.
