Kamen no Ninja Akakage — About this game
"Masked Ninja Akakage" is an action game for the Famicom that incorporates exploration and tool selection into side-scrolling battles. Operate Akakage to advance through the town and forest, obtain information and items at Karakuri Tomizou's hideout, and aim for Genma Castle where Koga Genyosai is located. At first, you will pass through the scenes in order, but in the next stage, you will focus on exploring by choosing a path and going back and forth to various places to collect scrolls. You can use not only ninja swords and shuriken, but also bombs, ninja techniques, and items that summon friends. However, there is a limit to the number of times ninja techniques and tools can be used, and there is also a time limit to the assistance of Aokage and White Shadow. Rather than having three players fight together all the time, it is a game where you choose the abilities you need, centering around Akakage.
