A retro game as good as the best platforms from the 8-bit era

Oniken is a platform action game honoring the 8-bit era of the 80s and 90s. You become Zaku, a ninja mercenary hired by the resistance to fight an evil terrorist organization called Oniken. The whole universe of the game is reminiscent of the 8-bit era, with old-school script, graphics and soundtrack. The Oniken gameplay is simple, but in hardcore mode, it can be extremely difficult.
