Return of the Ninja is a platform game with stealth elements developed by Act Japan and published by Natsume for the Game Boy Color in 2001 as a spiritual successor to 1990’s Shadow of the Ninja. A mysterious army has attacked the land of Koga and stolen an ancient and sacred scroll. As a highly trained ninja, it’s up to you to find out who is behind the trouble and recover Koga’s precious treasure.

To accomplish this, you’ll need to recover six secret ninja tools hidden from the invaders. The enemy army may outnumber you a thousand to one, but you are a master of stealth – and every military leader knows that a blind enemy is a vanquished foe. The player takes role of a ninja (either the male Tsukikage and or the female Saiyuri), using the D-pad to move and the buttons to jump and attack.

Various special items called Shinobi Tools need be collected to master the five arts of ninjutsu (Earth, Wind, Fire, Water, and Heaven) and proceed through the game. Guards may alert the others and can be avoided. The player’s rank at the end of each stage is determined by how fast the level was completed and how many times the protagonist has been spotted by human enemies, and cards can be awarded to the player.
