Sasurai no Ninja

Sasurai no Ninja is an action game where you play as a ninja known as Akakage (Red Shadow) who sneaks into Tarosa Castle, avoiding attacks by the Aokage (Blue Shadow), Shirokage (White Shadow) and bring back the stolen scroll (Secret Book). You must get into the castle, retrieve the stolen scrolls (5 scrolls in total), and come back. When the Aokage appears, your shuriken will not hit it because it's invulnerable, and the blue shadow will thrust its spear at you. In each room, there is a candle in the center, which must be lit to see the opponent. There is a pit or a suspended ceiling somewhere in each room, and if you go near it, you will hear a sound, so avoid it and go through. When you have the scroll, return to the initial position. When you step on the corpse of the Shirokage, you fall down and die. If you are in the wrong position to kill the Shirokage, you will not be able to go to the upper floors. If you jump on the suspended ceiling, you will fall and die. As you progress to the next floor the difficulty increases. You can't throw a shuriken in front of you, and you also can't throw shurikens while you are stuck to the ceiling.
