Battle With the Dark Ninja is the final stage from Alex Kidd in Shinobi World.
Details[]
The first area of the stage is set on a bamboo forest. The path is full of slopes where the player must dodge cannonballs and small platforms. If the player falls on a pit it will reach an underground area.
The second area is set inside of a base. Here the player must navigate single screen rooms which have traps on them, along with rematches against Kabuto and Robster in two of these rooms.
