Play Jajamaru no Daibouken (Japan) (Rev 1) Online

Jajamaru no Daibouken is a 1987 Nintendo Entertainment System release from Jaleco, a side-scrolling action game that fits right in with the platformers and quirky adventures of its era. It doesn't try to reinvent the wheel, but it has a distinct charm that makes it stand out among other NES titles from the late 80s.

You control a young ninja named Jajamaru, tasked with rescuing a kidnapped princess by navigating through a series of themed stages. The gameplay involves running, jumping across platforms, and throwing kunai at enemies like snakes, birds, and other fantasy creatures. A couple of its signature mechanics include wall climbing, which allows you to scale certain surfaces to reach higher areas or avoid hazards, and screen by screen progression where each section must be cleared before moving forward. The pacing is brisk, though the controls feel a bit floaty and take some getting used to; the difficulty is moderate but can spike unexpectedly in later levels. It feels lighthearted and a little strange, but consistently engaging once you adapt to its rhythm.
