“Katame Ninja” by Jaime Gifte, MetalZebra & Jaime Rabid.
“[A fast-paced] arcade game […] [with] one button [controls]. Our main character is a [one-eyed] ninja facing waves of [yōkai] in order to clean the ancient japanese scroll.”
I admit it: I was not able to completely finish “Katame Ninja”, as the second stage was way too difficult for me to survive. But you should play this amazing game anyway, because it feels so juicy! With its one button control scheme (any button you want) it gives such a great feedback. You just jump from one wall to another by pressing the button on the walls and if you press it mid-air, you will throw your weapon. You can also hold the button a bit longer at the walls to jump higher.
Try to avoid the spikey monsters who run down the walls from time to time and slaughter the evil spirits and demons, which possess lanterns, umbrellas and other everyday objects. Who knows, maybe you will not just defeat the mid-boss like I did, maybe you are even able to face and destroy the final boss? [PLAY]
