Ninja Jajamaru Kun/Gameplay

Controls

Items
Items can be found by breaking the breakable segments of the floors above you with your head. Not every segment will contain an item, but those that do will show the item once the segment is destroyed. The item will remain in place until the next segment is destroyed.

Ninja Art
Ninjakun can invoke a special Ninja Art known as the giant from summon. He can do this if he manages to collect three different power-ups out of the four available. They must be distinct power-ups. For example, if you find Medicine, Speed Ball, Medicine, Tram Car, the Ninja Art will not be invoked until the Tram Car is collected. The Ninja Art is invoked instead of the regular effect that the power-up would provide. Alternatively, you will also invoke the Ninja Art for every fourth extra life you collect.
