Player
Throughout the game, you take control of the ninja known as Ryu Hayabusa. As a trained and highly skilled ninja, Ryu possesses a lot of power and abilities. Learning how to tap into that power and use those abilities correctly is pivotal to your success.

Ryu has two means of attacking: his primary weapon is his katana, which he can rapidly swing to strike any enemies immediately in front of him. He can also make use of secondary weapons like throwing stars or bursts of flames, but only if he possesses enough spirit points to utilize them. He must collect these spirit points from blue and red tiles which he must liberate from item containers placed throughout each stage. Abilities require different amounts of points to use, see the ../Items/ page for more information.

Ryu is also incredibly agile, and can jump incredible distances. If he jumps towards a wall or a ledge, he can grab on to it and hold on. From there, he can launch himself in the opposite direction. He can use this technique to reach higher locations which are otherwise out of reach.

Ryu can sustain a number of hits before he succumbs to his wounds. A health meter is displayed at the top of the screen which indicates how much damage Ryu can handle before he loses a life. Ryu will also instantly lose a life if he falls through a gap at the bottom of the screen, regardless of how much health he has left. You will also lose one life if the timer runs out before you complete a stage. Ryu starts the game with two lives in reserve, and he can gain more chances by finding extra life items. If he loses all of his lives, the game is over, but you have the opportunity to continue as many times as you like.
